Merge branch 'pypi_bugfix' of https://github.com/crazyscientist/osc

Workaround/fix for pypi deployment via travis.

Note: I cannot really "review" this change because I have no clue about
travis. Since the current pypi deployment via travis does not seem to
work, merging it does not seem to be a problem.

Probably fixes: #884 ("osc pypi artifact is not up to date")
