[xfstests PATCH v4 5/5] overlay: correct scratch dirs check

["zhangyi (F)" <yi.zhang@huawei.com>]

Tests that use _overlay_scratch_mount_dirs instead of _scratch_mount
should use _require_overlay_scratch_dirs 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, we need
to call _overlay_check_scratch_dirs with the correct arguments.

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.
