Make it possible to disable the creation of the kubectl/crictl symlinks

If k3s_create_kubectl_symlink is set to false the kubectl symlink will
not be created.

If k3s_create_crictl_symlink is set to false the crictl symlink will not
be created.

By default the symlinks will be created. The default behavior is not
changed.
