    Use site-packages for our PYTHONPATH
    
    God I hate setuptools. Jenkins now fails with...
    
      The installation directory you specified (via --install-dir, --prefix, or the
      distutils default setting) was:
    
        /tmp/stem_test/lib/python3.7/site-packages/
    
      and your PYTHONPATH environment variable currently contains:
    
        '/tmp/stem_test'
