* do_split_packages and package_do_split_locales dynamically add
packages in order of appearance of os.walk() or os.listdir().
This order varies between multiple build hosts (and probably
also between successive builds).
* Sort the list of dynamically added packages, to get a consistent
and reproducible order.
* This reduces the diffs in buildhistory and improves
comparability between builds.
