sanitizer_common: fix ParseUnixMemoryProfile test linking on Mac

[dvyukov]

Summary

The ParseUnixMemoryProfile function is defined only for a subset
of platforms. Define the test for the same set of platforms.

Also disable the test for 32-bit platforms b/c the pointer
values used in the test are 64-bit and don't fit into 32-bit uptr.
