I discovered other .exe in python3, so this updated patch deletes them.
Since I modify the python from commencement.scm by changing a phase in
python-2.7, I decided to also change the definition there to remove the
offending files.

I managed to build up to python-3.9 without any issue, but haven't
tested building more than a handful of python packages.
