examples/service_cores: check cores before run

The service core samples has varied profiles created to run on specified
lcore count. The patch adds the check before each run, to ensure
example has sufficent lcores to be added as service cores on given run
profile. If sufficent cores are not found, the run is skipped with user
notification.
