mmap: Don't use mmap by default on OS X.

It has little benefits in general, (esp. in our usecase) and huge disadvantages for files on network mounts.
"Basically, IOKit should be so fast and efficient, that there are few usecases left for mmap() on Darwin."
(cherry picked from commit 400b67361af4cbbf8a72acccad040a84c34b248d)
