Fix FMQ benchmark test.

Wait for the service to come up before running the test.
This should not be done for "real" HALs; test HALs needs
waitForHwService because they are not declared in manifest.

Test: Run test without service, test hangs (before this change,
      test will fail); then starting the service will
      resume the test, and it passes.
Test: Run with service, test passes
