Implement backport-<commit> target

For packages with a GitHub repo configured in options.conf, allow
downloading and applying backport patches via the 'backport-<commit>'
target. If given an abbreviated commit ID, it will still create a
backport-<commit>.patch file with the full commit hash, plus add it (if
it does not already exist) to the end of the series file.

Because this handles a single commit at a time, this should be wrappable
by a future Makefile target that applies individual commits to catch up
to a target tag, for example.
