add ${KUBE-ROOT} for file directory
**What this PR does / why we need it**:
If we using following command
```shell
cd hack
./test-update-storage-objects.sh
```
it would throw err about unable find file `examples\persistent-volume-provisioning\rbd\rbd-storage-class.yaml`.
I think we should add `${KUBE-ROOT} `for file directory, so that we can run command in relative directory.
