josar 82d126158e test/xtimer_hang: use xtimer_periodic_wakeup
When sleeping in the main function with xtimer_sleep not every percentage
will be printed as the sleep duration and the processing time added do
not result in full percentage values.

Using xtimer_periodic_wakeup ensures that every integer percentage is printed.
