Do not retrieve message details for TSIG

Fix forwarded TSIG message issue

The TSIG message was not validated correctly if the dns update message was forwarded by a slave.
The forwarded message get's a new ID, this means the TSIG signature is now invalid as the bytes that are calculated for the TSIG are different.
The TSIG record contains the original ID, so this replace the new id with the original ID and this makes the message valid again.
Better way of replacing a few chars - thx cmouse!

tracking of include files so we make distclean would work.  I just spent 30
minutes chasing a phantom bug because of this - I understand people love for
make distclean to work, but this price is not worth it. so dependency
tracking is back.
