CNAME doesn't exist at the zone apex. When we get an unsigned noerror
response to a direct query for a CNAME record, we don't yet know if this
name is zone apex. We already request the correct DS record in this
case, but previously skipped it at validation time, causing the answer
to appear bogus. Make sure to also consider the DS record for the query
name for negative replies.
Although being far from ideal and the first two test cases have to be run
before the setup phase otherwise they will fail, it still makes the test
suite look much better and easier to read
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
