[PATCH 3/5] diff_filespec: drop xfrm_flags field

[Jeff King <peff@peff.net>]

The only mention of this field in the code is by some
debugging code which prints it out (and it will always be
zero, since we never touch it otherwise). It was obsoleted
very early on by 25d5ea4 ([PATCH] Redo rename/copy detection
logic., 2005-05-24).

No savings here on 64-bit, since this ended up going to padding, but it
is what makes the next patch work.
