Fixed the -n option with _mingw32_debug_package macro
    
    The -n option was passed down to -debuginfo subpackage's %package and
    %description sections, but not to %files. This change fixes %files to
    work the %same way as %package and %description.
    
    Not sure yet if the -n option will get any use, but at least this fixes
    an obvious oversight.
