Remove traceroute6

traceroute6 requires inetd to run, that is quite a rarity nowadays.
Due this it has been disabled by default since 2615a52 ("build-sys:
change build defaults"), change released in s20190324.

Remove it because there is better implementation from Dmitry Butskoy [1].
Also it can be replaced by other tools, e.g. tracepath -6 or mtr.

Closes: #362
