[k8s_fedora_atomic] Make calico devices unmanaged in NetworkManager config for master node

In https://review.opendev.org/#/c/548139/, we did the same change for
worker node, because kubelet is also installed on master nodes, we need
the same configuration, otherwise, the pods on master nodes won't work
properly(lost connection or timout frequently).
