Tests that use _overlay_scratch_mount_dirs instead of _scratch_mount should use _require_scratch_nocheck instead of _require_scratch because these tests are either mounting with multiple lower dirs or mounting with non-default lower/upper/work dir, so _check_overlay_scratch_fs won't handle these cases correctly. So we introduce _overlay_check_scratch_dirs helper and should call this helper with the correct dir arguments for these non-default cases. This patch modify these tests to optionally call _overlay_check_scratch_dirs at the end of the test or after _scratch_umount to mount base filesystem only and run the checker.
