preload/posix: Use #ifdef for stat() and friends

stat(), fstat() and lstat() are often defined as macros instead of functions,
which makes them much harder to override.

They were commented out, and this patch changes that to individual #ifdef, so
they can be enabled on platforms which have them as proper functions.
