docker: drop docker-ce recipe

docker-ce is now the same as moby. We've had a warning for
quite some time now, so it is time to remove the recipe.

We don't RPROVIDE docker-ce in the docker-moby recipe as
part of this removal, as all docker packages have been
RPROVIDING "docker" regardless of the variant. images and
packagelists should be using that provider, not docker-moby
and docker-ce
