xfs/{243,245,272,274}: ignore raid alignment flags in bmap output

This test doesn't care about the RAID alignment status of the mappings
that it finds; it only cares about shared and unwritten.  Ignore the
mapping stripe alignment flags in the bmapx output.  This fixes this
test when the fs has su=128k,sw=4.
