Tests after 276 were failing because the background fsstress
hadn't quit prior to exit, devices couldn't be unmounted, etc.
Just use the same trick as generic/068 does, and use
a tmpfile to control whether the background loop keeps
running.
Also, no need to umount scratch at cleanup time, the scripts
do that for us.
