    CI: Handle precompiled headers in iwyu command line
    
    I'm not sure if this has always been broken since we added precompiled
    headers, or if it's been broken recently by an iwyu upgrade. But
    apparently we need to add this extra argument, otherwise we get 'fatal
    error: gjs_pch.hh file not found'.
