Remove 'distribute' from the setup.py requirements

[b-a-t]

Hi, Mikhail!

Basically, any attempt to build the module with the modern tools fails with:

  Running setup.py bdist_wheel for distribute: started

  Complete output from command /srv/env/bin/python2.7 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-xugqIZ/distribute/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/tmpzmJYLRpip-wheel- --python-tag cp27:

.[91m  Failed building wheel for distribute
.[0m  Running setup.py clean for distribute

Distribute is ancient and outdated and similar projects removed it from the dependencies, see:
Running setup.py bdist_wheel for 'distribute' fails and distribute wheel build failure in setuptools>=20.2
