Truncate benchmark logs on re-run

Rerunning benchmarks did not truncate the benchmark log file before this change. New line would overwrite old lines, but you had to scan timestamps to figure out where exactly the new run was at. It also prevented `tail -f` to get real-time updates. This change truncates the benchmark file on each execution. Signed-off-by: Kern Walster <[email protected]>
