dns: increase TimeToVisible before DNS unavailable warning (#13317)
Updates tailscale/tailscale#13314

Some users are reporting 'DNS unavailable' spurious (?) warnings, especially on Android:

https://old.reddit.com/r/Tailscale/comments/1f3l2il/health_warnings_dns_unavailable_what_does_it_mean/

I suspect this is caused by having a too low TimeToVisible setting on the Warnable, which triggers the unhealthy state during slow network transitions.
