Duperemove is a tool for finding duplicated extents and submitting
them for deduplication, and it supports XFS. This case trys to
verify the integrity of XFS after running duperemove.

Thanks for Eryu's review.
V2 changed $TEST_DIR/${seq}md5.sum to $tmp.md5sum.
I didn't move this case to generic, due to duperemove tool only supports
Btrfs and XFS for now.
Thanks,
Zorro
