Steve Kuznetsov 6778af8a77 pkg/build: improve source finding message ...

Previously, users were not told where `kind` was looking for the
Kubernetes source, making the error message not actionable:

```
$ kind build node-image
ERROR: error building node image: error finding kuberoot: could not find kubernetes source
```

Now, we expose that information so the user can ensure we locate it.
