meta-ampere: mtjade: set MAC Address from FruDevice

FruDevice service is always running no matter if entity-manager is used
or not. It scans for all FRU EEPROMs, parse and store information into
dbus.
This commit changes to get BMC MAC Address from FruDevice data instead
of ipmi-fru-parser.

Tested:
1. Clear environment in u-boot, boot BMC to Linux and check if the
eth1addr variable is set with value from FRU.
2. Change BMC MAC address from FRU's Board Extra. Reboot BMC and check
if the eth1addr variable is set with new BMC MAC Address
