Use static uid/gid for systemd-{resolve,network}
    
    Clearly we have static uid/gid allocated so let's actually use them.
    
    egrep 'systemd-resolve|network' /usr/share/doc/setup/uidgid
    systemd-network 192     192     /               /sbin/nologin   systemd
    systemd-resolve 193     193     /               /sbin/nologin   systemd
