dnsrend 0.08 (new formula)

dnsrend is a DNS message dissector, showing excruciating detail to diagnose
malformed message contents.
Thanks Mike. It works replacing bin with libexec.
The chmod is apparently necessary, otherwise it fails.
There's another problem: the file $HOMEBREW_PREFIX/bin/dnsrend is not removed upon uninstall. I think it's because that file is not tracked automatically by brew. Maybe if we can "tell" brew to track it, as an executable, we can also avoid this issue and the chmod.

Again, any advice on this?
