Ensure BUILD_ROOT empty before actual check out during pre-receive about gitkube

[tirumaraiselvan]

Does this happen for each push? Does this happen even if you delete the gitkubed pod from the kube-system namespace (hence creating a new pod) ?

Once it's not clean, subsequent failed push won't clear the file (it's failed because of that not deleted file)

I resolve it by exec into the gitkube pod directly and rm the directory. Next time, I will delete the pod instead

Although It's not directly related to this issue, but my guess about failure reason to rm -rf $BUILD_ROOT is following error I got from time to time. Retry the push resolve the error.
