xfsqa test 166 fails on 64k page machine

test 166 output is dependent on page size (mmap related). Make
the output filter turn the output into something independent of
page size whilst checking that the output is valid.
Merge of master-melb:xfs-cmds:30702a by kenmcd.

  Make the file size and I/O size large enough that 64k pages are
  handled correctly.
