bench/parameter: Adding get_name_with_position()

This function is an helper to provide a unique name to benchmarks.
The current job position is padded to the current job name.

This commit:
- add this new function
- replace the existing occurences.
- change the output to report the name with position at runtime

Before :
[full_cpu_load] stressng/cpu/matrixprod(M): 1 stressor on CPU [0] for 60s
[full_cpu_load] stressng/cpu/matrixprod(M): 2 stressor on CPU [0] for 60s
[full_cpu_load] stressng/cpu/matrixprod(M): 4 stressor on CPU [0] for 60s

After:
[full_cpu_load_0] stressng/cpu/matrixprod(M): 1 stressor on CPU [0] for 60s
[full_cpu_load_1] stressng/cpu/matrixprod(M): 2 stressor on CPU [0] for 60s
[full_cpu_load_2] stressng/cpu/matrixprod(M): 4 stressor on CPU [0] for 60s
