Local testing on a idle and loaded system (compiling DPDK with all cores) always completes after 1 ms. The wait time for a service-lcore to finish is also extended from 100ms to 1000ms. The same timeout waiting code was duplicated in two tests, and is now refactored to a standalone function avoiding duplication.
