Subject: Encapsulate decision to keep lava session in runbenchmark.sh

This script knows whether it has cleaned up as it wants to. It now
sends a different signal to lava.sh to tell it to terminate with
job cancellation. We default to NOT cancelling the job, so if
anything goes wrong we will be able to investigate.
