Somewhere along the line, we started trying to add packages to the live
environment of flavor "preinstalled" images. But:
- we don't build preinstalled images for any flavors
- the preinstalled images for projects like cloud images and wsl are
explicitly excepted from this code
- the only desktop project we do produce preinstalled images for, Ubuntu
on Raspberry Pi, uses ubuntu-image for building so this code is never
reached
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.

On armhf and arm64 the QEMU virt machine provides the serial console as an
emulated AMBA PrimeCell UART which the kernel refers to as /dev/ttyAMA0.
Consider this when constructing GRUB_CMDLINE_LINUX_DEFAULT in file
/etc/default/grub.d/50-cloudimg-settings.cfg (LP: #2036730).

lp: #2037567. starting in kernel 6.5.0.1006, there's been an update to
apparmor features. Creates the 6.5 kernel directory, fully populates
with feats checked from a machine running 6.5.0.1006 installed from
proposed (as of 20230927).
Now that kernel names use expected -generic flavour, and kernels are
installed in the live layer, we can go back to stock behaviour of
auto/build noticing that binary hooks are called on a live layer and
executing the extraction & rename of the kernel flavours.
BTW we can even later expand that to support 2 generic abis, and
calling the bigger one the hwe generic such that can also remove
./live-build/ubuntu-server/hooks/04-kernel-bits.binary.
This fixes ubuntu arm64+x13s that is unable to find
ubuntu-x13s.kernel-laptop as due to this hook, which currently
produces ubuntu.kernel-generic in error which is not at all expected
by ubuntu-cdimage. Also this unbreaks producing oem & intel-iot
images, although we will build these in 24.04 only next.
This reverts ubuntu daily-live to use `--linux-flavours
laptop-generic-hwe-22.04` instead of `--linux-flavours none
--linux-packages=none --initramfs=none`, like it did in lunar and
pre-canary-image or images that install kernel in live layer.
Fixes: c00bbf3fb3 ("desktop: place kernel in the live layer")
