Add missing test for btrfs quota groups feature,test idea is to create
a parent qgroup that groups some subvolume groups, we try to write
some data into every subvolume and then check if we exceed parent
qgroup's limit size.

v1->v2:
	switch into new helper _run_btrfs_util_prog()
	use 'XFS_IO_PROG' instead of 'dd'
