Add alternative names for the server binaries to hyperkube

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

Right now one can't swap a server image to the hyperkube image without touching the `command` field in the yaml spec, and that's daunting and leading to extra and unnecessary logic for example in kubeadm.

This makes the hyperkube image directly swappable, so now `/usr/local/bin/kube-*` is a portable first argument (or simply `kube-*` if there's a shell).

**Special notes for your reviewer**:

**Release note**:

```release-note
Align the hyperkube image to support running binaries at /usr/local/bin/ like the other server images
```
