Calculate RFC7217 link-local style addresses the same way as
slaacd(8).
RFC 7217 states (section 5, page 9):
| The Interface Identifier is finally obtained by taking as many
| bits from the RID value (computed in the previous step) as
| necessary, starting from the least significant bit.
Problem in slaacd pointed out by semarie@.
