As I figured out a while back, the seabios firmware font is
nearly the same as our console font (eurlatgr) but not quite,
significantly its @ character is different (shorter). We
already have a root_logged_in variant for the firmware font,
but we now need one for user_logged_in as well. The Atomic
installer image has had the Linux console fonts stripped from
its payload, so it's now using the firmware font, and user_
logged_in isn't matching - see
https://openqa.fedoraproject.org/tests/461 .

Run the cloud_atomic_canned test (on an F23
post-release nightly, as it's not appearing for Rawhide
nightlies ATM) and confirm it now passes.
