The feature caused tests to fail when it was enabled.

- https://github.com/kubernetes/kubernetes/issues/78628

Work is in progress to fix the feature, but until that work is complete,
we will disable it in the GCE scripts.

There's a difference between the kubernetes-src.tgz build from
`make bazel-release` and `make quick-release`. The quick-release does
not have a `kubernetes/` prefix and hence essentiall tarbomb(s) the
directory when someone tries to untar it.
