ktest.pl: Add total test run time to output

Browse Source 
It can be interesting to know what the total time of all the tests took.
Instead of just seeing the time for each individual test, at the end of
the test (even on failure) show the total time the test took to complete.
This can also help identify if something has changed in the setup that
should be investigated if the times suddenly increase drastically.
