    LinuxKPI: add the "dummy" includes directory to builds
    
    While we could add the dummy includes directory manually to only the
    drivers needing it, it seems a lot easier to simply add it to all
    without any expected harm.
    
    This is needed for more drivers (and to remove some #ifdef in current
    ones) with empty header files being present not yielding errors.
