[Results] Update results report for non RTApp workloads
Created by: derkling
The results reporting for non RTApp workloads uses an old table formatting style which has been updated to a more readable one only for RTApp based workloads.
We should make sure that the table generated for non RTApp workloads (e.g. using the perf_bench wlgen class) is updated to use the same template adopted for RTApp based experiments.
This issue is somehow related to #8 (closed)
