Log Message:
Import BSD-licensed diff from FreeBSD to replace GNU diffutils

Ported to NetBSD, compiler warnings fixed, and some unnecessary
features (for the purpose of replacing our GPLv2 diff) have been
stripped out.

Non-default at the moment, requires building with MKBSDDIFF=yes.

PR bin/59798 We are still using GNU diffutils
