Robert Collins d7379df8b8 Enable --offline support for Ubuntu root images. ... When --offline is set elements should not revalidate cached data. The ubuntu element had not been updated to match this. SHA checking is also skipped as we only move a new cached file into place when the hash matches, and we might download a new hash before updating the image cache, which would cause persistent --offline failures.
