[PATCH] generic: add fiemap test that does prealloc

[Josef Bacik <jbacik@fb.com>]

I noticed that btrfs wasn't setting unwritten on prealloc test, and then
subsequently noticed that we weren't testing fiemap on prealloc extents with the
fiemap-tester.  This patch adds another test that does the same as generic/225
only with prealloc enabled.  Thanks,
