    greeter: add freedesktop URI prefix
    
    This allows using freedesktop prefix, in addition to the
    exisiting gnome, gitlab and github, with the --clone option.
    
    It is mapped to https://gitlab.freedesktop.org/, the GitLab
    instance hosted by freedesktop.org, which is the home of many
    projects, including Wayland, D-Bus, GStreamer, Cairo, and Mesa.
