update-staging-godeps: only mangle staging repos in staging Godeps.json

- this re-adds non-staging k8s.io/* repos to the staging Godeps.jsons
- x-outs instead of removing of staging dependencies in order to get a
  precise trigger for a complete godep restore+save run in the publisher
  bot.

The first breaks k8s.io/kube-aggregator's staging export.

The second potentially leads to inconsistent godeps in our exported staging repos.
