Previously the health check thread waited until we had finished
with the IDState to set `origFD` to -1, but:
* for the UDP client thread, the only difference it makes is that
`outstanding` will not be incremented if `origFD` is not -1,
which is not what we want since we are going to decrement it
* for the UDP responder thread, it actually increases the
likelihood of decrementing `outstanding` twice, once in the
responder threader and once in the health check thread.

This was especially likely to be an issue because the health check
thread used to call `gettime()` and to acquire a mutex before
setting `origFD` to -1.

The PowerDNS Recursor shuffles answers randomly, so no single A record gets overloaded. This logic also took care not to shuffle a CNAME record until after the name it points to, because we theorized this would upset some resolvers.
Our logic however assumed all the CNAMEs would initially be at the front of the packet. We'd start our shuffling after skipping all the CNAMEs up front. It now turns out that sometimes we end up with a 'CNAME A CNAME A' packet to shuffle.
This would happily shuffle the last three records. With this PR, we put the CNAMEs up front explicitly before commencing the shuffle. Closes #4339.

Still to be investigated: why didn't this bite us before?
