python3: Split setuptools into separate source package

Packaging setuptools from a separate source package allows it to stay
updated with upstream.

Host setuptools will remain installed as part of python3. Host
setuptools is used in a much more controlled way and so is less critical
for it to track upstream.

setuptools was in a separate source package that was removed in
a53d0c5a403d1669e2cf6c59c2be6a9d3ed633a0; this work is not based on that
earlier package.

+Setuptools is a fully-featured, actively-maintained, and stable library
+designed to facilitate packaging Python projects.
+
+It helps developers to easily share reusable code (in the form of a
+library) and programs (e.g., CLI/GUI tools implemented in Python), that
+can be installed with pip and uploaded to PyPI.
