Hi,

The kfreebsd-10 (kernel) packaging distributes a source tarball in
kfreebsd-source, a binary arch-indep package.

Some of these files are patched during the build, so the file and
directory timestamps in the tarball are not reproducible.

This patch will clamp timestamps to be no later than the latest
debian/changelog entry (replacing an earlier, incomplete fix).
