trafgen: Don't modify optarg/argv

Follow commit bed9b6bb ("netsniff-ng: Don't modify optarg/argv").

We shouldn't modify optarg (and thus argv) since it's e.g. used to
display the commandline string in `ps'. Since strtoul() reads until it
encounters the first non-numeric character and ignores the rest, we can
just revert from setting a NULL byte after the numeric part of the
string.
