Change py_binary to load from rules_python

To follow the (future) migration of the python rules out of the set of
native rules: bazelbuild/bazel#17773 .
This requires us to load the 'rules_python' module and while at it we
parameterize the 'py_binary' so it is possible for consumers to switch
to their own macros, following the model of pip_compile:
https://github.com/bazelbuild/rules_python/blob/9b2b70adba5431162401a97b2bbab1dc938e7245/python/private/pypi/pip_compile.bzl#L32

This solves loading errors:

    ERROR: Traceback (most recent call last):
