xfs/206: filter out reflink related outputs

Commit 13717ffc96 ("xfs/206: fix output when mkfs knows about
reflink") added extra lines to xfs/206.out to fit the mkfs output with
reflink support, but broke tests without reflink support.

Fix it by filtering out reflink related outputs, just like filtering out
crc related outputs in the test.
