m/n/c/clusternet: add clusternet node ip to lo

Without this address the kernel will send all traffic through clusternet
will with the external IP as source address, which prevents any access
from the k8s api-server to pods. By adding the address to the lo
interface, the kernel decides that this is the best match for the
generic clusternet route and uses it as source address.

Before: 10.192.1.2 dev clusternet src 233.252.0.1
After: 10.192.1.2 dev clusternet src 10.192.0.1
