meta-romulus: Add inventory-cleanup.yaml

The yaml add the "xyz.openbmc_project.Inventory.Item.Chassis" interface
to "/xyz/openbmc_project/inventory/system/chassis" object.

This is needed for bmcweb to correctly get the chassis id in
/redfish/v1/Chassis/.

Tested: Verify that /redfish/v1/Chassis/chassis exists on Romulus with
        this change. It was 404 without this change.
