Build hyperkube image using Bazel

**What this PR does / why we need it**: Before we had the hyperkube base image, it was difficult to build the hyperkube with Bazel. Now that we have the base image with all the necessary dependencies, this has become trivial.

This will enable federation jobs etc on prow.

**Special notes for your reviewer**:

**Release note**:

```release-note
