[MaraDNS list] How to get MaraDNS and Deadwood to talk to each other?

Note to self:  This regression is actually broken.  While, if properly
compiled, both MaraDNS and Deadwood can bind to and use IPv6 addresses
like fd4d:6172:6144:4e53::1 and fd4d:6172:6144:4e53::2, the SQA
regression no longer correctly tests for this.

MaraDNS needs to be compiled with special flags to use IPv6 and this
SQA test was never correctly updated to use MaraDNS 2's new IPv6
compile-time flags.

I should fix the IPv6 regressions one of these years.  I'm in no real
hurry to do so.
