ncsid: fix default wait time

The default wait time needs to shift with current timestamp, otherwise
the script will keep looping with 0 intervals and 0 wait time in RA, if
the initial loop does not capture any RA data.

Tested: bring down the interface to simulate the nic not ready, start
this script and verified that it loops every 10s. Then bring up the
interface, and see the route is setup with no issue

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.

ncsid: Find IPv6 gateway stably

Some environments have multiple gateways for the node to use. We want to
ensure that we aren't flip flopping between multiple gateways and lock
on to a specific gateway until it goes away.

Tested: Ran in an environment with multiple gateways and verified that
it did not switch after it acquired the first one.

Tested:
On a machine that has default route configured, manually deleted the
route, without this change it will stay broken. This change will bring
the route back in 1mins or so.

ncsid: update_ra_gw: Improve gateway discovery speed

The rdisc6 binary when run in a subshell buffers all of the output
instead of sending each line. This results in a long delay to figure out
the gateway address.

We can fix this by running it through `script`, which removes the
buffering and allows us to nearly instantly update our route.

Tested: Ran on our AMD Rome system and verified that the gateway was
quickly being updated.

The daemon is currently racy for setting the GW settings, don't depend

Tested: Ran on our AMD Rome system and verified that the gateway files
get generated correctly and the system was using the right routes.
