Cyril Roelandt 0a66c272cb Fix test_version on Python 3.4
Since Python 3.4, argparse has been printing the version on stdout rather than
on stderr as it used to. We should fix this now because:
- this is an issue when packaging oslo-config in Debian Sid, which uses Python
  3.4;
- it will be needed when Openstack switches to 3.4 anyway.
