Workaround 'value of REDIRECT_MALLOC/FREE unknown' cppcheck info messages

* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER]
(REDIRECT_MALLOC_F): New macro (defined to REDIRECT_MALLOC unless
CPPCHECK).
* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER] (malloc,
calloc, strdup, strndup): Use REDIRECT_MALLOC_F instead of
REDIRECT_MALLOC.
* malloc.c [REDIRECT_FREE && !REDIRECT_MALLOC_IN_HEADER]
(REDIRECT_FREE_F): New macro (defined to REDIRECT_FREE unless
CPPCHECK).
* malloc.c [REDIRECT_FREE && !REDIRECT_MALLOC_IN_HEADER] (free): Use
REDIRECT_FREE_F instead of REDIRECT_FREE.
