Bug#1120629: python-os-apply-config: please make the build reproducible

[Chris Lamb]

Source: python-os-apply-config
Version: 14.0.1-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: nocheck

Hi,

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

This is because the binary differs depending on whether the tests
are run or not. Specifically, the modification time of a file is 
different because of the patching of a file in debian/rules.

Patch attached.
