cogl-pango: Make color glyphs unaffected by foreground color

Making color glyphs affected by the foreground color makes them become
"tinted" on any other color than white. Make it sure we always paint
those white by checking the cached glyph value, the foreground color
will be reset on the next iteration through glyphs.
