fftools/ffmpeg_dec: don't try to copy side data from the decoder if it already exists in the output frame

Browse Source 
We can't use AV_FRAME_SIDE_DATA_FLAG_REPLACE here because the side data already in the
frame should have priority over the global one, so just ensure we don't copy any if
it already exists.

Fixes ticket #11468.
