manifests: updater mount the directory, not the socket

Quoting kube docs:

```
when accessing the `/var/lib/kubelet/pod-resources/kubelet.sock` from DaemonSet
or any other app deployed as a container on the host, which is mounting socket as
a volume, it is a good practice to mount directory `/var/lib/kubelet/pod-resources/`
instead of the `/var/lib/kubelet/pod-resources/kubelet.sock`. This will ensure
that after kubelet restart, container will be able to re-connect to this socket.

Container mounts are managed by inode referencing the socket or directory,
depending on what was mounted. When kubelet restarts, socket is deleted
and a new socket is created, while directory stays untouched.
So the original inode for the socket become unusable. Inode to directory
will continue working.
