PEL: Message_registry: System name as per new compatible interface

As part of the migration from IBMCompatible interface to the new
Compatible interface the PEL code is changed to use the new system name
format as 'com.ibm.Hardware.Chassis.Model.<system_name>'.

The message registry file still uses the old system name format
'ibm,<system_name>' which results parsing error of PEL message registry
callout JSON.

Hence modifies the message registry file to use the new system name
format.

Tested:
The dev_callouts file in /usr/share/phosphor-logging/pels/ have the new
system name format.
```
com.ibm.Hardware.Chassis.Model.Rainier1S4U_dev_callouts.json
com.ibm.Hardware.Chassis.Model.Rainier2U_dev_callouts.json
com.ibm.Hardware.Chassis.Model.Rainier4U_dev_callouts.json
```

Creating a PEL for SbeTimeout which leads to the PEL callouts as
expected:
```
"Callout Section": {
        "Callout Count":        "2",
        "Callouts": [{

        }]
    }
