flatpak_create_dockerfile: Enable the repository from the 'koji' plugin

With the switch to "Hybrid" modularity in Fedora, modules typically need
to pull packages from a base package set as well. The build tag of the
Koji target provides a way to pass in an appropriate base package set, so
we'll make odcs-client enable the 'koji' plugin, and the Dockerfile should
enable the resulting repository.
