generate systemd: use --cidfile again

Commit 9ac5267 changed the type of the generated systemd units from
`forking` to `notify`.  It further stopped using `--cidfile` and instead
intended systemd to take care of stopping the container, which turned
out to be a bad idea.

Systemd will send the stop/kill signals to conmon which in turn may exit
non-zero, depending on the signal, and ultimately breaking container
cleanup.

Hence, we need to use --cidfile again and let podman stop and remove the
container to make sure that everything's in order.

Fixes: #11304
