cri: propagate deprecation list to runtime status

Propagate the deprecation list to CRI runtime conditions.

The propagated conditions are visible via `crictl info`,
but not visible via `kubectl get nodes -o yaml` yet, although
the CRI API says "These conditions will be exposed to users to help
them understand the status of the system".
