Inform setuptools that Extensions are included (rapidsai#643)

Fixes rapidsai#641

As `setuptools`/`pip`/`wheel` will mark our package as pure (even though we put an extension module into it), make sure it doesn't by informing `setuptools` that `Extensions` are contained within. This should ensure that are wheels include the Python minor version they were built for.
