add a system test with an ADB loop

Browse Source 
Add a lame delegation to lame.example.org with only an A record
in the additional section; on failure, this will trigger a retry
with AAAA, which will loop. Test that dig returns SERVFAIL, in
addition to confirming that named doesn't hang on shutdown.
