    fc: Plug a memory leak
    
    pango_fc_patterns_get_font_pattern() returns a reference
    if prepare is FALSE, and otherwise returns a pointer to
    a pattern that is owned by the fontset. But in that case,
    we call FcFontRenderPrepare, making a new pattern.
    
    In either case, by the time we reach the bottom of
    pango_fc_fontset_load_next_font, font_pattern holds a
    reference we need to free.
