[FFmpeg-cvslog] avformat/iamf: Mark symbols as hidden

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Mar 13 15:45:52 2024 +0100| [62412cd75d41ba497b0c7b2bac7f94d514c82115] | committer: Andreas Rheinhardt

avformat/iamf: Mark symbols as hidden

Avoids .got entries for ff_iamf_scalable_ch_layouts and
ff_iamf_sound_system_map (whether they would have been
created otherwise depends upon the compiler and compiler
options).
