mpg123: update to version 1.29.3

Changes:

- libmpg123: Catch more NULL pointer arguments in LFS wrappers
  (most prominently: mpg123_feedseek(), bug 328).
- mpg123:
-- Fix regression that did _not_ enable --remote-err on -s anymore.
-- Fix typos in man page (thanks to Naglis Jonaitis).
-- Drop mixed-up value limits on remote control SEQ command. It is up to you
   if you want to distort your sound.
-- Add note about equalizer frequency bands to man page.
- build: add BUILD_PROGRAMS option to ports/cmake
