examples: make 10-ifcfg-rh-routes.sh self-contained
Don't call the 'if{up,down}-routes' scripts because in next Fedora versions network scripts will be deprecated and will not be present in the default installation. Instead, just copy and adapt the code from those scripts. https://bugzilla.redhat.com/show_bug.cgi?id=1618419
