avcodec/mpegaudiodata: Unavpriv mpa_bitrate and mpa_frequency tabs
These arrays have a size of 180 resp. six bytes. This does not
make it worthwhile to export them due to the overhead this occurs;
for x64 Elf/Linux/GNU: 2x2B version, 2x24B .dynsym, 24B .rela.dyn,
8B .got, 4B hash + twice the size of the name (here 20+23B).
Therefore these symbols are unavprived and duplicated for shared
builds.
