python: Use patch (from upstream) instead of inreplace

This patch is different than my earlier ad-hoc solution, but it took

can't directly link to the patch (from the mercurial web repo), as it
also changes the NEWS text and the patch fails to apply. Further, the
mercurial repo is only http (no "s").
