Address PR pkg/30957 with a new 'djbdns-listenmultiple' option to apply

these patches:

- Uwe Ohse's djbdns-1.05-multiip.diff for tinydns
- Dan Peterson's dnscache-1.05-multiple-ip.patch for dnscache

The patches came with different list separators, but this is pkgsrc! The
default separator for both is now a comma, and you can override it by
setting DJBDNS_IP_SEPARATOR. (Add that to BUILD_DEFS if the option was
enabled, and unconditionally add all the users and groups.) Bump
PKGREVISION.

While here, make djbdns-1.05-ignoreip2.patch fetchable via archive.org.
