[arch-projects] [devtools] [PATCH] archbuild/makechrootpkg: Delete var/lib/machines under subvolume

Some packages end up creating subvolumes through systemd-tmpfiles, (e.g.
systemd-nspawn,) so we need to delete those as well, but there's no way
to reliably list subvolumes under a certain subvolume relative to the
filesystem, so we need a hard-coded list.
