    cssprovider: Reimplement gtk_css_provider_load_from_path()
    
    Call gtk_css_provider_load_from_file() instead of the internal function.
    This has two advantages:
    1) It simplifies the code a lot
    2) It gets rid of GMappedFile usage. GMappedFile does not work
       everywhere, so this is finally portable.
