Add kernel modules needed by Calico

[tmjd]

• Enable ipset module CONFIG_IP_SET_HASH_NET
• Enable ipip module CONFIG_NET_IPIP

Fixes #1779
Addresses projectcalico/calico#1013

I've built the minikube.iso with make out/minikube.iso and was able to do minikube start --network-plugin cni --host-only-cidr 172.17.17.1/24 --iso-url file://$(pwd)/out/minikube.iso and was then able to deploy calico successfully to the resulting K8s cluster.

Can one of the admins verify this patch?
