Subject: [PATCH] Fix another dependency problem with httpbin and Python 3.4

Crazily, pip installs seem to be non-deterministic as installing httpbin
in https://travis-ci.org/github/wxWidgets/wxWidgets/jobs/765946720
pulled in werkzeug 0.16.1 which works with Python 3.4, but doing it
again tries to use werkzeug 1.x which isn't.

Fix the version explicitly to work around this.
