cmocka: realloc(ptr, 0) should act as free(ptr)

Currently, realloc(ptr, 0) does not free the pointer as specified by
'man 3 realloc':

    The realloc() function changes the size of the memory block pointed
    to by ptr to size bytes. [...] if size is equal to zero, and ptr is
    not NULL, then the call is equivalent to free(ptr). [...]

This causes a leak of the allocated memory, and tests that use this
particular realloc() pattern fail.
