The kayobe-tox-ansible job is failing in the swift-block-devices role
while formatting the Swift block devices as XFS. The error comes from a
change in xfsprogs [1]:
Filesystem must be larger than 300MB.
Bump size of backing file to fix the job.
Also make the kayobe-tox-molecule job non-voting as it is currently
broken.
