xfs/186: fix test for crc=0, ftype=1

Test 186 won't run when crcs are enabled, because
attrv1 is not allowed with crc=1.

However, ftype is still allowed with crc=0, so
this creates v3 directories, and xfs_db prints
them as such (along with the filetype), which
breaks the test output.

We can filter & replace to fix up the test in
this case.
