Restore kube-controller-manager settings lost in static pod migration

* Migration from a self-hosted to a static pod control plane dropped
a few kube-controller-manager customizations
* Reduce kube-controller-manager --pod-eviction-timeout from 5m to 1m
to move pods more quickly when nodes are preempted
* Fix flex-volume-plugin-dir since the Kubernetes default points to
a read-only filesystem on Container Linux / Fedora CoreOS
