Add /kubepods to cgroup mounting regex in entrypoint

[priyawadhwa]

This will ensure that the kubepods cgroup is correctly mounted, which
kubeadm uses. Without it, kubeadm init fails in Cloud Shell.

According to this article

Kubelet by default will always create the root /kubepods cgroup, which all Kubernetes pods are started within.

Also update kic to incorporate this change

fixes #9082
