Bug 1093874 2nd attempt

New pull request created for Bug 1093874, reverting dummy filechange commit
As these file share the same repo, is it worth it to make a another copy? Can't we make the same [kind of copy we do for atoms](https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/setup.py#L28). That is to say, copy the file when we run `setup.py` in a folder excluded via `.gitignore`?
