Fix crash in codec_lpc10 when MALLOC_DEBUG is enabled.

This switches codecs/lpc10/lpcini.c back to including "asterisk.h"
instead of <stdlib.h>.  lpcini.c allocates memory that is freed by
codec_lpc10.c, so it is important to use MALLOC_DEBUG allocator.
Added #define WRAP_LIBC_MALLOC to the start of the source to prevent
runtime symbol link error's.
