podman: add runit service
https://github.com/void-linux/void-packages/pull/36102

Description:
[Upstream Systemd service](https://github.com/containers/podman/blob/v4.0.2/contrib/systemd/system/podman.service.in) doesn't do anything special. `--time=0 unix:///var/run/docker.sock` is required, since we don't have socket activation.
