generic/388: randomly recover via read-only mounts

XFS has an issue where superblock counters may not be properly
synced when recovery occurs via a read-only mount. This causes the
filesystem to become inconsistent after unmount. To cover this test
case, update generic/388 to switch between read-only and read-write
mounts to perform log recovery.
