ncsid: Prefer fe80::1 gateway

Our labs and production environment normally use this as the gateway
address. We often have noisy lab networks with many bad gateways
advertising their presence. We know we generally prefer fe80::1 so we
switch to it when available.

Tested: On a noisy lab network and verified that the script correctly
locks onto fe80::1 and switches away from other gateways it receives.
