Support starting benchmark tasks using taskset on Linux
Our benchmark tasks must be modified to add a taskset
command to pin the CPU the benchmark will run on. This is needed because now CPUs come with performance cores and energy efficient cores, making it harder to have reliable results otherwise.
It's also needed by https://github.com/nodejs/build/issues/3657.
