dhcpcd service: order before network target
This reverts a change applied in PR #18491. When interfaces are configured by DHCP (typical in a cloud environment), ordering after network.target cause trouble to applications expecting some network to be present on boot (for example, cloud-init is quite brittle when network hasn't been configured for `cloud-init.service`) and on shutdown (for example, collectd needs to flush metrics on shutdown). When ordering after network.target, we ensure applications relying on network.target won't have any network reachability on boot and potentially on shutdown. Therefore, I think ordering before network.target is better.
