Fix HAX emulation.

The change at https://android-review.googlesource.com/#/c/84261/
broke HAX emulation under Windows and OS X, because the refactored
code didn't properly call hax_populate_ram() _after_ actually
allocating the virtual memory in the process' address space.

This patch fixes the issue.
