fix(node): setupos networking dependency (#3159)

Setting setupos.service to depend on
systemd-networkd-wait-online.service prevents a timing issue where
setupos.service runs before the networking has been set up.

If generate-network-config fails, setupos.service still runs. It just
hangs for a minute after generate-network-config fails before starting
setupos.service.
