run-test: '--time' option provide more details to user

'time.time()' module can only be used to calculate 'real' time taken by a
process. Therefore, I switched it to 'os.times()' module which helps in
getting additional info like "Total number of CPU-seconds that the process
spent in kernel mode" and "Total number of CPU-seconds that the process spent
in user mode".
