This allows a much more natural way of implementing unitttest-discover:
- unittest provides unittest/__init__.py
- unittest-discover provides unittest/__main__.py
It also fixes an bug where unittest.py previously detected the presence of
unittest-discover.py by importing an checking for the ImportError. But that
could also be raised by a missing dependency. Now when you run
`micropython -m unittest` without unittest-discover, you get
`ImportError: no module named 'unittest.__main__'`, and without the
required deps, `ImportError: no module named 'argparse'`.

In order to make this more suitable for non-unix ports, the discovery
functionality is moved to a separate 'extension' module which can be
optionally installed.
