Python 3 - Fix checking of string types in unittest2 module.

This patch actually introduces a dependency from unittest2 to
six.  This should be ok since both packages are in our own
repo, and we assume a sys.path of the top-level script that
can find the third party packages.  So unittest2 should be
able to find six.
