Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that python-defaults generates substvars that are not reproducible

For example, this is in python-tgext.admin:

│   │   │   │ -Depends: python (>= 2.7), python (<< 2.8), python:any (>= 2.6.6-7~), python-pkg-resources, python-sprox, python-toscawidgets, python-turbogears2
│   │   │   │ +Depends: python (>= 2.7), python (<< 2.8), python:any (>= 2.6.6-7~), python-sprox, python-toscawidgets, python-pkg-resources, python-turbogears2

Patch attached. The equivalent patch is already in dh-python FYI.
