[PATCH] xfstests: add filter to 200 accommodate changed mount output

[Eric Sandeen <sandeen@xxxxxxxxxx>]

The mount binary changed its output w.r.t. red-only devices, and
stopped referring to a "block device."

This broke at least test xfs/200; add a common filter to remove
the "block device" from older mount binary output, and change
the 200.out file to match.
