python3: Setuptools 0.9.7 and rm old ones

Remove old setuptools installations that may still fly around and be
listed in the easy_install.pth. This can break setuptools build with
zipimport.ZipImportError: bad local file header

This does not always happen, but if the easy_install.pth points to an
egg with an older version. Removing all setuptools and distribute
remains inside the homebrew global_site_packages is safe.
