automation: delete code related to Python 2.7 support
The building of Inno and WiX installers took a python_version argument
that allowed us to specify "2" or "3" for the major Python version. Since
we no longer support Python 2, we can delete this argument and everything
feeding into it.

#require test-repo pylint hg10
Run pylint for known rules we care about.
-----------------------------------------
There should be no recorded failures; fix the codebase before introducing a
new check.
Current checks:
- W0102: no mutable default argument
