python: update type hints for mypy 0.930

Mypy 0.930, released Dec 22, changes the way argparse objects are
considered. Crafting a definition that works under Python 3.6 and an
older mypy alongside newer versions simultaneously is ... difficult,
so... eh. Stub it out with an 'Any' definition to get the CI moving
again.

Oh well.
