benchtests: send non-consumable data to stderr

Browse Source 
Non-consumable data, alias data not related to benchmarks, should be sent to
the standard error, thus pipelines can work as expected.

	* benchtests/scripts/compare_bench.py (do_compare): write to stderr in case
    stat is not present.
	* benchtests/scripts/compare_bench.py (plot_graphs): write to stderr in case
    timings field is not present. Also string showing the output filename goes
    into the stderr.
