HW-Isolation: Fix Additional Data Uri

The guard records could be associated with hidden or visible PEL. The
additional URI for visible pel would be
/redfish/v1/Systems/system/LogServices/EventLog/Entries/<id>/attachment
and for the hidden ones it has be
/redfish/v1/Systems/system/LogServices/CELog/Entries/<id>/attachment

So before adding the AdditionalDataURI, check for the hidden property of
the PEL and add the URI accordingly.

Tested and found it works as expected
