[PATCH 6/8] python: allow short names for variables on older pylint

[John Snow]

Pylint >= 3.0.0 disabled this feature, but older pylint does not: allow
short names by default by using a regex to do so.

Incidentally, this removes the need for most of the allow list we had before, so
remove most of that, too.
