Old btrfs qgroup test cases uses fix golden output numbers, which limits
the coverage since they can't handle mount options like compress or
inode_map, and cause false alert.
Introduce _btrfs_check_scratch_qgroup() function to check qgroup
correctness using "btrfs check --qgroup-report" function, which will
follow the way kernel handle qgroup and are proved very reliable.
