Remove workaround for mbcs bug in distutils
setup.py
has a workaround for http://bugs.python.org/issue10945 , which only effects up to Python 3.3
coala minimum version is Python 3.4, so this workaround can be removed.
But before it is deleted here, it should be pushed upstream to https://github.com/moremoban/pypi-mobans/issues/46
