ko: Fix output of 'kubectl rollout status'

This is the same fix as 6e93717597 for ko.

If running `kubectl rollout status` command, the output is like:
```
  deployment "nginx-deployment" successfully rolled out
```

The corresponding kubectl code also shows it according to e95e378e59/pkg/polymorphichelpers/rollout_status.go (L89)
