decoder_ffmpeg: constify codec variables

Fixes the following compile warnings: decoder_ffmpeg.c: In function ‘init_vaapi’: decoder_ffmpeg.c:135:22: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 135 | AVCodec *codec = avcodec_find_decoder(avctx->codec_id); | ^~~~~~~~~~~~~~~~~~~~ decoder_ffmpeg.c: In function ‘ffdec_init_sw’: decoder_ffmpeg.c:149:22: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 149 | AVCodec *codec = avcodec_find_decoder(avctx->codec_id); | ^~~~~~~~~~~~~~~~~~~~
