Alexander Potapenko c97434ecaf Disable wrapping memcpy() on Mac OS Lion, where it 
actually falls back to memmove.
In this case we still need to initialize real_memcpy, so we set it to
real_memmove
We check for MACOS_VERSION_SNOW_LEOPARD, because currently only Snow
Leopard and Lion are supported.

Alexander Potapenko f504602a0f Disables testing memcpy() on Mac OS 10.7, 
where memcpy() in fact aliases memmove() and thus calling it with
overlapping parameters is not an error.
