Tune kernel parameter for babeltrace benchmarking

idle=poll prevent the kick in of sleep state. This is not that important
for babeltrace since it is mostly userpsace, single threaded and cpu bound.

cpufreq.off=1 ensures that we do not play with the frequency of the cpu.

numa_balancing=disable makes sure weird numa interaction happens.
