[READY] Fix nose --ignore-files option

[micbou]

We were only ignoring the file . instead of all files starting with a dot when running the tests. With this PR, we also ignore the setup.py file since:

• it's ignored by default (the default being (^\.|^_|^setup\.py$));
• should make the life of maintainers easier (see the Arch Linux JediHTTP package for instance);
• we may consider adding this file in the future.

Thanks to @yan12125.
