Get UUID from inventory subtree

Currently, the UUID is getting from the first object path that
includes "Common.UUID" interface. But the UUID can be obtained
from the MCTP/FRU...
The system UUID should be got from the object path that has the
prefix "xyz/openbmc_project/inventory". This commit updates
subtreepath parameter from "/" to "/xyz/openbmc_project/inventory"
to fix the issue.

Tested:
1. Get UUID via Redfish
   /redfish/v1/Systems/system
2. Get UUID via IPMI command
   $ ipmitool mc guid
The UUID obtained in steps #1 and #2 is same.
