cgroup v1: change the default runtime to io.containerd.runc.v2

Browse source 
The previous default runtime `io.containerd.runtime.v1.linux` is being deprecated (https://github.com/containerd/containerd/issues/4365)

`io.containerd.runc.v2` is available since containerd v1.3.0.
 Using v1.3.5 or later is recommended.  v1.3.0-v1.3.4 doesn't pass `TestContainerStartOnDaemonRestart`.

Fix #41107
Replace #41115
