fstests: btrfs: use proper filter for subvolume deletion

Test cases btrfs/208, 233, 276 does not use _filter_btrfs_subvol_delete()
to process "btrfs subvolume delete" command's output. So, the following
diff occurs even with a previous fix.

btrfs/208       - output mismatch (see /host/btrfs/208.out.bad)

Let them use the filter and fix the output accordingly.
