disable flake8 test for this repo

[gengjiawen]

Should we add this rule in https://github.com/nodejs/gyp-next ?

Also should we disable flake8 test for this repo since gyp sources is an upstream project ?

Better safe than sorry. How long does a flake8 run take? If the run takes less than 5 minutes then I see no reason to eliminate it.

The issue now is that rules on both side are not consistent. Works fine on gyp-next and breaks on this repo.

We may need to align the rules in the long run.

Put the rules in setup.cfg and copy that file when we copy the Python code.
