Ok, these tests were initially written before these helpers were
hoisted into a common location, so it makes sense to clean them out
now.

I think it's another common helper that's over in common/log now. I
suspect it was just reminiscent of the test case I modeled this after
at the time. It should likely come out now too.

I think I had borrowed this from the protofile test case
(tests/xfs/019). But yes, if the file creation were to fail, I think
the mkfs command will just error out. It should be fine to take it out
if folks prefer. Thanks for the reviews!
