support/testing: test_python_django: use the timeout_multiplier value

As reported by our gitlab runtime test [1] and on the mailing list
[2], the test_python_django is failing due to django server taking a
lot of time to start. Since the django server is started in background
through pexpect, we can't easily wait for the last startup line:

"January 01, 1970 - 00:00:41

Django version 3.0.4, using settings 'testsite.settings'

Starting development server at http://0.0.0.0:1234/

Quit the server with CONTROL-C."

In the failing gitlab job, we don't see such lines.

If we increase a lot the timout, the test passes.

Use timeout_multiplier introduced by [3] in order to adjust the
timeout.
