run.sh installs SIGINT and SIGTERM traps to gracefully stop runner (#2233)

Browse Source 
* run.sh installs SIGINT and SIGTERM traps to gracefully stop runner

* replaced trap to force wait for child processes and to send kill to run-helper instead of Runner.Listener

* run with signal handling if RUNNER_MANUALLY_TRAP_SIG is set

* Update src/Misc/layoutroot/run.sh
