scripts/installer: support all distros and osesXe/test-install-script-libvirtd

As well function entirely headlessly. This was used to test the work
done in #1922. The only thing it fails on is Debian bullseye, which will
need more work due to it being prerelase. More work is required there
but that is out of scope for now.
