btrfs-progs: test: add a check test case for verity items

Leo recently fixed a false alerts in btrfs-check where verity items are
reported as unknown items.

Add a test case for such case, the image is generated by enabling
fsverity on a small file, which will have VERITY_DESC_ITEM and
VERITY_MERKLE_ITEM items to trigger the previous false alerts.
