This commit extends the timeout for service_may_be_active()
from 100ms to 1000ms. Local testing on a idle and loaded system
(compiling DPDK with all cores) always completes after 1 ms.

The same timeout waiting code was duplicated in two tests, and
is now refactored to a standalone function avoiding duplication.
