meta-google: systemd: fix unwanted waitings in network-wait-online

networkd wait-online services will wait for all ethernet interfaces to
be up by default. Some interface will never be ready because it is
unused Currently only rsyslog is waiting for this service so it should
be fine to just remove this service.
