docker-archive: Add support for kaniko

[avisiedo]

Added the pointed out changes at #318 by @labooner

Tested into the workstation by:

docker run --rm -it -v "$PWD:/workspace:z" -w /workspace gcr.io/kaniko-project/executor:debug --destination="dive-test:kaniko-latest" --force --no-push --tarPath .data/test-kaniko-image.tar
./dist/dive_linux_amd64/dive --ci docker-archive://.data/test-kaniko-image.tar

But it needed some changes (not included as I didn't research the impact):

Hoping this help.
