Split out the network-scripts
    
    The network-scripts are now removed from the RHEL 8 base installation (and
    possibly Fedora too). Let's remove them, so that we don't end up in a situation
    where we install unneeded files into an unowned directory.
    
    The boolean weak dependency is utilized to make life easier for those still
    relying on the legacy network service and to avoid breakage on upgrades.
