fw_update:Enable software object creation without EM

Previously, software objects were only created if Entity-Manager
provided an inventory path mapping. Without EM config, the function
would error out and no software object would be created.

This change introduces a fallback board path for platforms where
Entity-Manager is not configured or unavailable, allowing firmware
inventory to work independently of Entity-Manager.

Entity-Manager configuration may be missing in environments where EM
is not installed, disabled, or deliberately excluded—for example, in
minimal or custom OpenBMC/PLDM deployments.

Tested: Software objects created successfully without EM configs on B40.
