    This fixes support for PCI domains in what should hopefully be a backward
    compatible way along with a change to libdrm.
    
    When the interface version is set to 1.4, we assume userspace understands
    domains and the world is at peace. We thus pass proper domain numbers
    instead of 0 to userspace.
    
    The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
    ignoring domains in the later case (well, except on alpha of course)
