Bug 1901033 - image_builder: update kaniko and skopeo. r=glandium

Adjust kaniko arguments passed in by build-image:
- pass --cache=true to kaniko, otherwise it seems to look for an image named
  "parent" on docker hub instead of looking at the tar we put in the cache dir
- pass a cache-repo to kaniko, otherwise it refuses to enable caching
  (GoogleContainerTools/kaniko#374)
