Add ability to use public GCR image

Kaniko by default used to configure the GCR credential helper however
this caused Kaniko to fail when trying to use a base image from a public
GCR image. This patch makes it possible to use public GCR images as base
image when using docker even when you're not authenticated to GCR.
