zone.lisp: Tighten up the default SOA parameters.

Reduce all of the timeouts.  The TTL is halved from eight to four
hours, because I think I can cope.  And the secondary synchronization
parameters are reduced partly because everything uses `NOTIFY' these
days, and partly because I'm using DNSSEC with short validity periods,
and holding on to records for longer is just pointless.
