Don't update pbr's setup.py

Due to the fact that we'd like to keep pbr's requirements in sync with
global requirements we should disable syncing of setup.py for pbr.

* existing tests fixed by adding standard setup.cfg file;
* new test case added for syncing pbr project (with pbr like setup.cfg file).
