fstests: fix fallocate commands that need the unshare switch

Browse Source 
We re-added the UNSHARE flag to fallocate, so go make sure that all
the unshare tests actually check that the installed copy of xfs_io
supports the 'funshare' command and that the underlying filesystem
understands the flag, and change the tests themselves to use
funshare.
