Under Python 3, __pycache__ is used, and is not cleaned up.
It is also not necessary to clean it up anymore, since those .pyc files
cannot be imported without a .py files unlike what happens under Python 2.

This is starting to get quite repetitive though.

Always run Python scripts through the same interpreter.
Also simplify the running of pyflakes and flake8, as recent versions all
support execution through python -m. Due do the many variations among
distributions, it makes the whole thing much simpler.

This should make running tests faster, as we do not remove all .pyc
files anymore!
