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 nodejs/build#3657.

const child = fork(path.resolve(__dirname, job.filename), cli.optional.set, {
execPath: cli.optional[job.binary],
});
