test(iroh-net): increase timeout for local swarm discovery test (#2574)

## Description
The `local_swarm_discovery` test was reliably timing out when run on the
linux CI. After checking the logs and NOT finding any evidence that
anything goes wrong, I increased the timeout and can no longer trigger
the failure.

## Change checklist

- [x] Self-review.
