I don't think I need these because I don't actually require this functionality
from xfs_io. I did try and use xfs_io for this test, but the way the
threading needs to work I ended up having to write my own C program. So,
even if xfs_io happens to be old and without fpunch, for example, as long as
fallocate can use FALLC_FL_PUNCH_HOLE I think the test should do the right
thing.

Also need "punch collapse zero" groups.
I'm assuming I should still add my test to these 3 groups, even though I'm not
getting this functionality via xfs_io?
Thank you for the review, I'll address the rest of your comments in v2.
