fix kubepassword export folder

[saintdle]

Fixed issue where auth folder is exported from bastion host to local folder under the newly created auth folder, meaning you now have auth/auth this also means terraform destroy did not work as it complained about not finding the kubeconfig and kube-password files locally.

Confirmed the auth/auth path existing for me. Also received feedback that

terraform-equinix-metal-openshift-on-baremetal/main.tf

Line 171 in 2ca53a9

program = ["/bin/bash", "-c", "[ -f \"${path.root}/auth/kubeadmin-password\" ] && echo \"{\\\"password\\\":\\\"$(cat ${path.root}/auth/kubeadmin-password)\\\"}\""]

was affected by this.
