In CI, determine loop devices dynamically to avoid conflicts with Ubuntu snaps

Browse Source 
Introduced when updating CI to Ubuntu 20.04, Ubuntu snaps consume
loop devices, which conflict with out assumption that /dev/loop0
will always be unused. Changed to request a dynamic loop device from
losetup, though it would have been nice if Ubuntu snaps allocated
from the last device or something.
