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
