Fix machineID getting for vmss nodes when using instance metadata

**What this PR does / why we need it**:

When instancemetadata is for Kubelet on master nodes , kubelet is not able to register itself with errors:

```sh
Unable to construct v1.Node object for kubelet: failed to get external ID from cloud provider: not a vmss instance
```

This PR fixes this issue by composing standard instance ID for such nodes.
