Fix image used by some kops presubmit jobs

The old image has not been updated in almost a year [0] and is still running Go 1.11:

```
docker run --entrypoint=/usr/local/go/bin/go gcr.io/k8s-testimages/gcloud-in-go:v20190125-cc5d6ecff3 version
go version go1.11.5 linux/amd64
```

We have open PRs [1] which are not compatible with go 1.11 which is causing their presubmits to fail.
This switches those jobs to use the same kubekins image as the E2E jobs.
I see other projects using the same kubekins-e2e image for non-e2e jobs as well [2].

The new image has Go 1.13 as we expect:

```
docker run --entrypoint=/usr/local/go/bin/go gcr.io/k8s-testimages/kubekins-e2e:v20191219-72db7a6-experimental version
go version go1.13.4 linux/amd64
```
