This commit fixes a sporadic failure of the service_autotest
unit test, as seen in the DPDK CI. The failure occurs as the main test
thread did not wait on the service-thread to return, and allowing it
to read a flag before the service was able to write to it.
The fix changes the wait API call to specific the service-core ID,
and this waits for cores with both ROLE_RTE and ROLE_SERVICE.
The rte_eal_mp_wait_lcore() call does not (and should not) wait
for service cores, so must not be used to wait on service-cores.
