    gitlab-ci: Add test stage
    
    The test stage runs the whole meson test suite inside Xvfb inside a dbus
    session. Running inside Xvfb is required as the cogl, clutter and mutter
    tests require to run on top of X11; the dbus session is required to make
    mutter succeed in owning names on the bus.
    
    This also updates the Dockerfile to include packages needed for running
    tests.
