fix: install LXD snap from stable/ubuntu-<version> channel (LP: #2036725)
In the past, we'd directly snap install lxd which defaults to
the latest/stable channel. However, whilst working on enhancing
unminimize, it was observed that we install this snap from
the stable/ubuntu-<version> channel instead.
This was also noted as a failure when running the CTF tests:
`lxd installed from latest/stable, not stable/ubuntu-23.10`

Fix unminimize to correctly list packages (LP: #1996489)
Prior to dpkg/1.21.0, there was a bug where dpkg -V/--verify
couldn't list all the correct packages correctly but with
that being fix and in archive since Jammy, this works perfectly
but the syntax to report the missing files have changed. It
just prints 'missing' now. With that new format, we can now
fix the regex to simply list the packages.
With this patch, the unminimize script works flawlessly
on a minimized image.

fix: don't modify ssh_config for ubuntu-cpc projects (LP:1968873)
Modifying directly /etc/ssh/sshd_config creates "problems" when
upgrading eg. from Focal to Jammy because the upgrade will ask the
user what to do with the modified config. To avoid that, put the
custom configuration into /etc/ssh/sshd_config.d/ so the upgrade of
openssh-server can just replace /etc/ssh/sshd_config without asking
the user.
(cherry picked from commit b54d24ff3310f7ace00ab08e0dacfdc89e026f1c)
LP: #2034253 Grub is found to use lsb_release or default to Debian.
buildd does not have lsb_release, so Debian was the GRUB_DISTRIBUTION.
that ends up with issues with the EFI path
