Revert "travis: Add workaround for a tox/virtualenv/six issue"

This reverts commit d450e926de65e5517293d38ec3ad2a1a17020d05.

Was fixed by making tox depend on newer versions of six so the package
gets installed/updated automatically now when installing tox.  There is
also some ongoing work that tries to make virtualenv work with older
versions of six.
