Traceroute doesn't consider host-timeout

[tremblerz]

On running sudo nmap --traceroute google.com -Pn -sn -d --host-timeout 0.001s whole output table of traceroute got printed, this is obviously impossible if host-timeout had been working for --traceroute further, I have checked inside the code of traceroute.cc and probably there isn't any provision for checking timeout.

I'm not sure that host timeout matters very much for traceroute, since only 1 packet gets sent to each target during that phase. The rest of the packets get sent to intermediate hops. That said, maybe you should bring this up as a discussion question on the nmap-dev mailing list.

Just as an update, we're planning to at least add a check to skip the traceroute if the host has already timed out.
