openpower-pels: Create guard using libguard

Replace CreateWithEntityPath D-Bus method with guard library calls for
creating guard entries, as CreateWithEntityPath is not an approved dbus
method.

Tested and the guard record is created with the corresponding PEL id

```
before injecting the error
root@p10bmc:~# guard -l
No unresolved records to display

After injecting error, the guard is created using the PEL ID
root@p10bmc:~# guard -l
ID         | ERROR      | Type            | Path

root@p10bmc:~# peltool -l
