LibGfx: Remove 'QOIImageDecoderPlugin: ' prefix from error messages

What the component which did the actual decoding is called is not
relevant for the error, and would be rather distracting once we show
decoding error messages e.g. in ImageViewer (instead of just silently
failing).
Also makes them more consistent as many already don't include it - a
mistake which is now turned into a feature :^)
