Re-add systeconfig file

This file is wholely managed by openshift-ansible. However if we remove
the file from the RPM entirely then that will delete the file during
upgrades to the newer version. So leave the file in the package with
empty contents. The %config(noreplace) directive will ensure that RPM
doesn't replace local modifications when upgrading.
