Update node status instead of node in kubelet

#31730 added code for the Kubelet to reconcile the existing and new nodes in order to annotate existing nodes with the annotation for controller-managed attach-detach.  However, it used `Update` instead of `UpdateStatus`, which changes the operations the node's token needs to be permitted to use.  Using `UpdateStatus` is functionally equivalent and maintains the same set of permissions nodes need to have today.

I'm adding this with the 1.4 milestone because it is a follow-on to a 1.4 PR and fixes a downstream bug (which won't surface to Kube).
