fa7166759789c1282609ff3ab2e80d4f70910a9f ci: Move travis workarounds to .travis.yml (MarcoFalke)

Pull request description:

  It seems odd to have travis related workarounds in the general ci config files. Fix that oddity by moving the travis related workarounds to the travis yaml file.

  For unexplained reasons, this should also work around and thus close #19171
