Subject: Skip distutils tests

   ... when setuptools is installed.

It seems that recent setuptools override distutils, which ends with such errors
         ext = v.get_extension()
 >       assert 'distutils.extension.Extension' in str(ext.__class__)
 E       assert 'distutils.extension.Extension' in 'setuptools.extension.Extension'
