xfstests: improve test 286 for repeated unwritten/hole extents.

Browse Source 
Enlarge the test coverage of 286 to includes file mapping with repeated
hole/unwritten/unwritten_without_data/data intersections.

Those two new sub-tests could help verifying the current seek_data/seek_hole
improvements.
