selftests/mm: remove READ_ONLY_THP_FOR_FS in khugepaged

Browse source

Change the requirement to a file system with large folio support and the
supported order needs to include PMD_ORDER.

Also add tests of opening a file with read write permission and populating
folios with writes.  Reuse the XFS image from split_huge_page_test.
