avfilter/af_sidechaincompress: Honour query_formats API, fix segfault
Just like the sidechaingate filter, the sidechaincompress filter overwrote the channel layout and channel count of its output in its config_output callback to match the channel layout of its main input instead of linking the main input and its output together in its query_formats callback. This is an API violation that can lead to segfaults, as in the following filtergraph, where stereotools rightly expects stereo, yet receives only mono: [in]aformat=channel_layouts=mono,aformat=channel_layouts=stereo|mono[out];\ [out][in2]sidechaincompress,stereotools Fix this by linking the channel layouts of the main input and the output in query_formats and remove the code overwriting it in config_output.
