kubeadm selfhosting: fix pod spec mutation for controller-manager 

Modified command line options --authentication-kubeconfig and
--authorization-kubeconfig to point out to the correct location
of the controller-manager.conf

This should fix this controller-manager crash:
    failed to get delegated authentication kubeconfig: failed to get
    delegated authentication kubeconfig: stat
    /etc/kubernetes/controller-manager.conf: no such file or directory
