Please enable subunit support on Python 3.x

[Arfrever Frehtes Taifersar Arahesis]

python-subunit has been supporting Python 3 for long time, so code in lines 33-46 in setup.py can be simplified.

Also 'extra' dictionary is no longer used.

Probably some code in tox.ini can be simplified.

If I run zope.testrunner's tests with python-subunit in sys.path on Python 3.x, I get a bunch of test failures that say

    AttributeError: '_io.StringIO' object has no attribute 'buffer'

or

    AttributeError: '_io.StringIO' object has no attribute 'buffer'

all in deep in subunit's make_stream_binary(). I'm guessing zope.testrunner's test fixture (subbed-out sys.stdout?) is incompatible with the assumptions that subunit makes.

Help would be appreciated.
