If cluster member node name is not resolved (for any reason) using host dns, but becomes available soon after the dns query, it will still be unresolvable for a long time.

fix: decrease maximum negative ttl for dns responses
75bcdde 
The maximum negative ttl (ttl for non-existent domain responses) was set to 1 hour, which is
too long. This PR decreases the maximum negative ttl to 10 seconds.

Also update CoreDNS module while we are at it.

Closes siderolabs#8631
