meta-romulus: Add ipmi inventory sel config

phosphor-ipmi-inventory-sel provides a yaml config for sel events, and
Romulus was using the default one, which makes the sel events not
mapping to the expected devices.

Provide a yaml config that matches Romulus system.

Tested: Inject error and check SEL logs are correctly parsed by
        openbmctool.py in openbmc-tools/thalerj.
