This fixes the race that happens in rktnetes when pod B invokes 'kubenet.SetUpPod()' before another pod A becomes actually running. The second 'kubenet.SetUpPod()' call will not pick up the pod A and thus overwrite the host port iptable rules that breaks pod A. This PR fixes the case by listing all 'active pods' (all non-exited pods) instead of only running pods.
