Decrease the number of individual sites listed in log.

Browse Source 
By default 30 first servers are listed individually to system log, and
then a count of the remaining items. With e.g. a NXDOMAIN based adblock
service, dnsmasq lists 30 unnecessary ad sites every time when dnsmasq
evaluates the list. But the actual nameservers in use are evaluated last
and are not displayed as they get included in the "remaining items" total.

Handle the "local addresses only" separately and list only a few of them.
Remove the "local addresses only" from the general count.
