Changes from v2:
* Added 'Created subvolume...' into 203.out to match the subvolume creating command
* Changed awk to $AWK_PROG, suggested by Eryu
* Changed _run_btrfs_util_prog to $BTRFS_UTIL_PROG, suggested by Eryu
* Use _scratch_unmount instead of executing umount by hand, sugested by Eryu
* Created a local function to delete and list subvolumes, suggested by Eryu
Changes from v1:
* Added some prints printing what is being tested
* The test now uses the _btrfs_get_subvolid to get subvolumeids instead of using
plain integers
