tests: fixed compilation of qstring benchmark on mac

On Mac, MAP_ANONYMOUS and MAP_POPULATE are not defined.

Fix MAP_ANONYMOUS by defining it to MAP_ANON.

Fix MAP_POPULATE by removing it, because its usage was unnecessary in
this code (the page was explicitly faulted in a few lines later anyway).
