Some DNS servers for which dns_nsupdate.sh is applicable (such
as dyn.com's 'Standard DNS' TSIG update mechanism), require that
the zone be set during the nsupdate transaction. Therefore we
add a new environment variable NSUPDATE_ZONE which is used to
set the zone for the DNS TSIG transaction.

When debug is enabled, also use nsupdate's debug logging
so that the user can see potential issues with the nsupdate
transaction.
