dbus-sdr: Remove the use of undocumented Inventory.Decorator.FruDevice

Remove the use of Inventory.Decorator.FruDevice interface and use
Inventory.Decorator.I2CDevice instead.

https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/xyz/openbmc_project/Inventory/Decorator/I2CDevice.interface.yaml

The two interface serve the same purpose.
