unminimize: Use lxd-installer to install LXD itself (LP: 2036725)
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.

Merge utkarsh-lunar-sru-1996489 into ubuntu/lunar [a=utkarsh] [r=andrew-cloke,philroche]
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: 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`
