pkg/autoupdate: repull image if other containers failed

If two containers use the same image and one rolled back (i.e., tagged
the old image again), make sure to repull the image for the other
container.

Once an image has caused a rollback, it may be worth marking this image
as broken and not update any other container using it but that is
outside of the scope.
