run-tests: '--time' option provide more details to Linux users

As our tests execute in child processes, this patch uses os.times()
module in replace of time.time() module to provide additional info like
user time and system time spent by child's processes along with real elapsed
time taken by a process.

There is one limitation of this patch. It can work only for Linux users and
not for Windows.

"os.times" module returns a 5-tuple of a floaing point numbers.
1) User time
2) System time
3) Child's user time
4) Child's system time
5) Ellapsed real time

On Windows, only the first two items are filled, the others are zero.
Therefore, below test cases does not break on Windows but instead gives the
zero value.
