HW-Isolation: Fix Additional Data Uri

[deepakala-k]

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//attachment and for the hidden ones it has be
/redfish/v1/Systems/system/LogServices/CELog/Entries//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
