python3: don't sort the manifest in create_manifest
Instead of sorting the entire manifest when it is updated, use OrderedDict to
preserve the order of fields. This means that packages can be ordered in the
manifest to allow non-trivial FILES assignments (such as a package that picks up
pieces of other packages)
The manifest has been regenerated with the new stable ordering, and
distutils-staticdev moved above distutils so the packaging rules work as
expected.
