kinder: make sure worker nodes also get a patches dir created

During join of worker nodes kinder always passes to kubeadm
JoinConfiguration that has a Patches.Directory.

If the directory does not exist kubeadm will error out.
Always create the directory for worker nodes.
This was already done for the "init" node and for "join" control
plane nodes.
