Commit 875fa96f / change-id Ief0040f6 unintentionally tries to enlarge
the "machines00" LV when LXC is the default container technology which
fails due to the Debian automated installation having assigned all the
space within the associated "vmvg00" VG.
As the intention of the aforementioned commit was to apply when
systemd-nspawn was used, codify that explicitly in a `when:` condition
on the problematic Ansible task.
