Failing CPC tests show that the preseeded apparmor features don't
include policy:unconfined_restrictions for the 6.5 kernel. This change
adds the feature preseed.

fix: Fix calls to `unminimize` if lxd-installer package not present (LP: #2049723)
The unminimize script will try to install the lxd snap using the shim script
`/usr/sbin/lxd` from the lxd-installer package.
Previously `unminimize` was using `snap`
to install `lxd` directly which was being diverted by diverting the `snap` command.
This is no longer the case so we can remove `/usr/sbin/lxd` from the lxd-installer package
if it exists and then redirect any calls to `/usr/sbin/lxd` to `/bin/true`

Altering a file maintained by a package can lead to unexpected behaviou expecially in
this case where packages are being removed and added.
Instead use `dpkg-divert` to allow us to mock `lxd` to `true` to allow `unminimize` to work
without error and to avoid installing of the `lxd` snap.
`--force` implies that we wish not to fail `rm` even if the file is not present.
This was not our intention and as such can be removed.
Also use short option `-v` for verbose output as per the test of the code base.

Commit 3b2eeb017153cbb wrongly backported a change to not modify
/etc/ssh/sshd_config . The correct fix from ubuntu/master is
3b2eeb017153c where the file is named 60-cloudimg-settings.conf
instead of 10-cloudimg-settings.conf.
This fixes problems with cloud-init which does write
50-cloud-init.conf which should have higher priority than the provided
file from the image.
By invoking LXD, lxd-installer will install LXD from the right
place, thereby make it simpler for us to not hardcode the
channel and manually snap install it.

fix: Enable snap preseeding with ppc64el images where /boot/vmlinux is used instead of /boot/vmlinuz. (LP: #2038957)
ppc64el still uses /boot/vmlinux so we need to determine the boot file name as non ppc64el use /boot/vmlinuz. This
is then used to determine the kernel major minor version installed so that the correct apparmor features can be used
during snap preseeding. This preseeding was failing for ppc64el for the mantic 6.5 kernel as the /boot/vmlinuz
being checked did not exist.
