    Add a GitLab CI manifest
    
    This manifest will allow us to run some basic checks on each commit and
    integrate build status properly into the GitLab UI. This does not need
    to contend with build.gimp.org per se: we can use the CI for Merge
    Requests to perform basic checks, while the build server does the heavy
    work.
