1) _require_fiemap and _require_xfs_io_command "fiemap" do the
same thing, but some test cases use the former and some use
the latter, so i feel they should be unified.
2) The number of helpers like this is slowly growing, but it's
easy to simply use _require_xfs_io_command directly and just
specify the command we want to check.
This is just a cleanup for keeping it simple.

The test case will check SHARED flag returned by fiemap ioctl on
reflinked files before and after sync.
Normally SHARED flag won't change just due to a normal sync
operation.
But btrfs doesn't handle SHARED flag well, and this time it won't
check any delayed extent tree(reverse extent searching tree)
modification, but only metadata already committed to disk.
So btrfs will not return correct SHARED flag on reflinked files if
there is no sync to commit all metadata.
This testcase will just check it.
