build(mirror): Define GitLab mirror in source (#21)

Configure the gitlab repository target in source.

Create a reference to the GitLab mirror location of this repository is source. Although it would be nice to not bundle in the references to the location of a repository into the repository, there exists leakiness in other ways in the repositories. This is done to assist in some cross-service mirroring experiments.
