hackbench: Wait for hackbench to complete

As the rtevalModulePrototype::run() method will call Hackbench::_WorkloadTask()
every second without ensuring hackbench is running first - wait for hackbench
to complete before returning from _WorkloadTask().

This approach was chosen here as Hackbench is normally a shortliving process
anyway.
