Daniel Bertalan 4195a7ef4b Kernel: Return EEXIST in VirtualRangeAllocator::try_allocate_specific() ...

This error only ever gets propagated to the userspace if
MAP_FIXED_NOREPLACE is requested, as MAP_FIXED unmaps intersecting
ranges beforehand, and non-fixed mmap() calls will just fall back to
allocating anywhere.

Linux specifies MAP_FIXED_NOREPLACE to return EEXIST when it can't
allocate, we now match that behavior.
