meta-ibm: meta-genesis3: phosphor-ipmi-fru: Fix config

After rebasing on upstream the config wasn't properly updated
to use genesis3 custom YAML config. Update the config to actually
read the MAC from EEPROM and set it on Dbus.

Tested: MACAddress field is set on DBus ans phosphor-networkd
        applies the MAC address to the network interface.
