[PATCH 0/1] MR2879: loader: In macOS preloader, don't unmap the reservation for builtin DLLs.

[Tim Clem (＠tclem)]

This seems to be a holdover from when ntdll was a Mach-O winelib
binary, so the reservation needed to be removed before it was
dlopen'd. Now that it's PE, unmapping the reservation is unnecessary
and leaves time for the system to reclaim it, thus requiring the
potentially problematic relocation of ntdll.
