It would make sense to use an analogous mechanism to 32bit router id,
just use IPv6-LL address instead of IPv4 address. See 'router id' / 
'router id from' options and function if_choose_router_id().

One issue is that if BIRD is started during boot then IPv6-LL addresses
may not be available immediately after start due to waiting for duplicate
address detection.
