[PATCH 2/6] rteval: Fix stressng --taskset argument parsing

The --taskset option and its CPU list argument were being combined into
a single string argument ('--taskset 0,1,2'), but stress-ng expects them
as separate arguments ('--taskset', '0,1,2').

This caused stress-ng to fail to parse the --taskset option when a
cpulist was specified.

Fix by using extend() instead of append() to add both the option and its
value as separate list elements.
