Test that an incremental send operation does not skip overwrite ref
for inode 256, it's always exist.

This test exercises scenarios used to fail in btrfs and are fixed by
the following patches for the linux kernel:

"Btrfs: incremental send, fix don't skip inode 256 in overwrite_ref"

Tests should have a description that non-developers can understand
(like QA people for e.g.).
I doubt most QA people know how send works internally.
