gnu: python-args: Patch reference to basestring.

Hi Maxime,

I **totally** forgot about this one! Seems like no one is using it.
`python2-args` also builds. But no package seems to depend on it anyway.

Regards,

Tanguy

* gnu/packages/python-xyz.scm (python-args)[source]: Use the latest version
from the git repository to get the test suite.
[home-page]: Update URL.
[native-inputs]: Add python-nose.
[arguments]: Replace reference to basestring with str. Invoke nosetests.
