[Fuego] [fuego-core 2/7] ftc: fix test process is not killed when fuego test times out

From: nguyen thi huong <[email protected]>

- Currently, fuego kill main process and does not kill test process when test times out
  In that case, test process still runs but fuego test result is not available
- Revise implementation to kill all test processes and printout the result
