DW5821e: if no carrier config installed, DEFAULT carrier GUID should be exposed
When no carrier config is installed in the device, we should still export a GUID flagging the carrier as "DEFAULT", so that fwupd GUID matching works and we allow running the firmware upgrade.
See https://github.com/fwupd/fwupd/issues/2200 for context.
