[PATCH 02/20] tests: don't put loop control files on the scratch mount

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

If we're doing write/overwrite/snapshot/resource exhaustion tests on
the scratch device, use the test directory to hold the loop
termination signal files.  This way we don't run infinitely because we
can't create the flag due to ENOSPC.

v2: put the control files in /tmp, not $TEST_DIR
