mpg123: upgrade 1.33.3 -> 1.33.4

Changelog:
mpg123: In terminal control, ignore 7-bit escape sequences to avoid spurious actions, e.g. when hitting cursor keys.
ports/cmake: Avoid possibly conflicting use of SIZEOF_OFF_T CMake variable when embedding mpg123 with other projects using cmake and different off_t semantics.
