support specifying MB FRU eeprom path
The MB FRUID should be exposed with ID 0 for BIOS to get the data to
fill out SMBIOS table during POST. However, current IDs depend on the
ordering of the FruDevice object paths.
(1) Using the object with "Type: EEPROM" and "Name: MB FRU" in the
EntityManager to figure out the MB FRU eeprom path. Other FRUIDs still
depend on the ordering of the FruDevice object paths.
example of the entity-manager config:
```
{
"Address": "$address",
"Bus": "$bus",
"Name": "MB FRU",
"Type": "EEPROM"
},
```
(2) For System GUID that BIOS populates into SMBIOS table during POST,
also use the MB FRU eeprom path instead of the hardcoding eeprom path.
