Instruct flake8 to avoid certain well-known directories created by
python tooling that it ought not check.

Note that at-present, nothing actually creates a ".venv" directory; but
it is in such widespread usage as a de-facto location for a developer's
virtual environment that it should be excluded anyway. A forthcoming
commit canonizes this with a "make venv" command.
