tests/fate: Add a VPK regression test for a zeroed channel layout

Browse Source 
Generate the 21-byte sample from issue #24290 and copy it with
ffmpeg. avformat_find_stream_info() must keep the container channel
count at 80 instead of replacing it with 0 after adpcm_psx fails to
open; the decoder cannot be opened, so ffprobe -show_entries is not
usable here.
