Don't require win_unicode_console on Python 3.6

It looks like the changes Drekin's win_unicode_console makes have
essentially been integrated into Python 3.6, so it will use the Unicode
APIs for Windows console access by default. See [PEP
528](https://www.python.org/dev/peps/pep-0528/).

So we shouldn't need to load WUC on Python 3.6, and it may even have
some strange interactions.
