restore: fix container restore into pod

Browse Source 
Currently, when Podman restores a container into a Pod, it always fails
with the following error:

    Error: cannot add container f96670b26e53e70f7f451191ea39a093c940c6c48b47218aeeef1396cb860042 to pod h2-pod: no such pod

This error occurs because r.state.Pod() is called in setupContainer()
with the Pod name instead of ID. This patch fixes this problem by
setting ctrConfig.Pod to pod.ID().
