When bisecting a performance regression using a config file, `./bisect_regression --config my_perf.conf` for example, the config file can contain Codespeed configuration which would instruct the 'aggregate.perl' script called by the 'run' script to output results in the Codespeed format and maybe to try to send this output to a Codespeed server. This is unfortunate because the 'bisect_run_script' relies on the regular output from 'aggregate.perl' to mesure performance, so let's disable Codespeed output and sending results to a Codespeed server.
