tools/hexnet: Put the new usage generator to use and remove prefixes for IPv4 and IPv6 

The prefixes were part of a planned feature but since a connection is
either IPv4 or IPv6 but never both, it would have been completely useless
to specify which to use. Instead, only TCP and UDP will need to be specified.
