generate systemd: support pods and geneartig files

Support generating systemd unit files for a pod.  Podman generates one
unit file for the pod including the PID file for the infra container's
conmon process and one unit file for each container (excluding the infra
container).

Note that this change implies refactorings in the `pkg/systemdgen` API.
