f158993 contrib: Update asmap link in seeds readme (Fabian Jahr)

Pull request description:

  I am moving all my ASMap related repositories to an asmap org. While there is a redirect in place that works for now, GitHub doesn't guarantee that it will keep working in the long term. So we should still fix the links.
