meta-romulus: Add callouts yaml config

Romulus was using the exmaple callouts yaml and it is just a dummy one.
Provide the real callouts yaml config for Romulus.

Tested: With the following commit, verify CALLOUT_INVENTORY_PATH is
        correctly set when CPU error is injected and the event is sent
        to BMC.
