Revert to single-dist setup.py and use virtual dependencies instead

The only reason why we produced different eggs was because we may want to
install easily an admin node without caring about dependencies of neo.client.

Multi-dist setup.py contains hacks and was overkill for NEO.

-# WKRD: Official Python packaging and buildout are not designed to build
-#       several binary packages from a single source one. This setup.py
-#       contains several hacks to work around this horrible limitation, and
-#       make it possible to develop several eggs in the same tree/repository:
-#       - in development mode, it behaves somehow like a mono-package
-#       - otherwise, sdist/bdist commands produces several packages
