Patch new coredns default config properly
Patch new coredns default config properly

https://github.com/kubernetes/minikube/pull/11404 introduced
a change in the coredns config core file, which leads to an
error with the current patching logic. The configuration file
may not contain the hosts plugin twice.

Be strict on the host.minikube.internal name,
allow different localhost IPs.
