Upgrade Kubernetes version deployed by RKE to v1.19.6

Manual system_images assignment in rke's cluster config
is dropped as for any particular kubernetes release Rancher
project holds a predefined, static map connecting Rancher's
Kubernetes version with particular system images, so it's
enough to define k8s version.
