lib500: verify timers relative each other 

As commit ce896875 fixed a timer that accidentally had been moved in
code and then returned a bad timer, the lib500.c code (used in test 500
and some others) now verifies 5 timers against each other to verify that
they have the correct relative values. We cannot compare against
absolute values as the timings will vary a lot.
