meta-facebook: fix ipv6-ll address

The correct MAC address of NCSI managerd ethernet interface is obtained
during NCSI config process. It will need run extra workaround to
regenerated IPv6-LL address based on new MAC address from NCSI.

Add service for checking the MAC address is correctly get from NIC card
via NCSI, then regenerate the IPv6-LL address.

Tested on Harma:
```
