[PATCH] Fix a build warning when USE_MMAP isn't set

[Jean Delvare]

Building with USE_MMAP unset results in the following warning:

util.c:158:13: warning: ‘safe_memcpy’ defined but not used [-Wunused-function]
 static void safe_memcpy(void *dest, const void *src, size_t n)
             ^~~~~~~~~~~

Only define the function when USE_MMAP is set.
