Much fix, very fix, wow

When doing installations without network, we need to ensure that we don't try
to perform apt operations that require internet. To do this in Plucky, we need
to temporarily copy the ubuntu.sources file to an ubuntu.sources.bak file. To
bring all of the previous commits in this upload together, we use the
bind-mounted /media/cdrom not only to install the correct GRUB packages, but
to ensure that we can still install them and any other packages on ship-live.

There has to be a better, more native way to do this. It works for now, but in
the Questing cycle, we're probably going to move some of these command-line
apt calls to be a consumer of the libapt C library (LP: #2107287).

+  * [pkgselectprocess] Ensure apt-cdrom command outputs have their own prefix.
+  * [checkpackage-backend] Simply pass through packages starting with "^" or
+    containing "*". For this cycle we can trust our distributors won't do
+    anything unusual, but next cycle, we need to perform explicit validation
+    on these items. If you are a downstream, please be careful.
+  * [pkgselectprocess] Ensure hasInternet is available as a local variable, so
+    we can use it.
+  * [pkgselectprocess] When running apt remove, use CPBE just in case.
+  * [pkgselectprocess] When doing installations without network, we need to
+    ensure that we don't try to perform apt operations that require internet.
+    To do this in Plucky, we need to temporarily copy the ubuntu.sources file
+    to an ubuntu.sources.bak file. To bring all of the previous commits in
+    this upload together, we use the bind-mounted /media/cdrom not only to
+    install the correct GRUB packages, but to ensure that we can still install
+    them and any other packages on ship-live. There has to be a better, more
+    native way to do this. It works for now, but in the Questing cycle, we're
+    probably going to move some of these command-line apt calls to be a
+    consumer of the libapt C library (LP: #2107287).

+
+  * [pkgselectprocess] When we are creating the final list of packages to feed
+    to "apt install," virtual packages which do not have a valid candidate are
+    included in this list, causing the installation to fail. When creating
+    this list, use FindGrp instead of FindPkg, and only add it to the list if
+    there is a valid candidate. Additionally, add these items to an unordered
+    set, to eliminate deduplication (LP: #2106773).
+  * [pkgselect] As a temporary measure until OEM is refactored in the 25.10
+    cycle, we need to ensure that Calamares and its necessary dependencies are
+    installed on the target, iff this is a stacked squashfs. We're doing this
+    in pkgselect instead of pkgselectprocess because pkgselect already knows
+    about stacked squashfses, it's what provides the final "additional install
+    list" to be considered by checkpackage-backend, and this is a temporary
+    fix anyway (LP: #2104343).
+  * [pkgselectprocess] To complement the last fix, ensure that Calamares ends
+    up on the removal list for non-stacked squashfses if and only if OEM is
+    disabled, and Calamares shows up on the install list only for stacked
+    squashfses which have OEM enabled. This nuanced approach ensures all
+    potential combinations have the intended functionality.
+  * [OEM] Ensure the final desktop file completing OEM is marked as executable.

+  * Bump Standards-Version to 4.7.2, no changes needed.
+  * [pkgselectprocess] If checkpackage-backend does not exist in the target
+    system, likely due to the use of stacked squashfses, ensure it temporarily
+    exists so it can be used in the install process. This fixes installation
+    of the Virtual Machine Manager when selected on the Customize menu
+    (LP: #2104243).
+  * [OEM] As a temporary stop-gap until this can be completely re-written next
+    cycle, ensure the sed call in the Calamares OEM setup refers to
+    pkgselectprocess, not packages. This was preventing the OEM processing
+    step (as opposed to just the GUI configuration) to be missing
+    (LP: #2104343).
+  * [OEM] [Kubuntu] In stage two, ensure we use Wayland, consistent with the
+    rest of the session scripts.
+  * [pkgselectprocess] Disable the dpkg trigger inhibition logic this cycle.
+    The original goal here was to de-duplicate some of the trigger processing
+    work, but it's obvious this needs more work. It's too premature to ship
+    right now, unfortunately.
+  * [Lubuntu] Remove the Dracut configuration so we fall back to the defaults
+    provided by the package. This is a no-op.
