Bug#1117494: python-can: please make the build reproducible

Source: python-can
Version: 4.6.1-1

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
python-can could not be built reproducibly.

This is because the documentation calls out to Python 2.x and the
error message that gets embedded in the documentation varies depending
on the shell (eg. dash vs. bash):

│ │ │ │ -/bin/sh: 1: python: not found
│ │ │ │ +/bin/sh: line 1: python: command not found

This is, in turn, caused by the debian/patches/python3.patch patch
being slightly incomplete, we also need to patch the can.bridge bit:
