local-up-cluster.sh: Use config file instead of flags for kubelet

Because /tmp/kubelet.log shows trailing log.

Flag --container-runtime-endpoint has been deprecated, This parameter should be set via the config file specified by the Kubelet's --config flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.
