[PATCH] traceroute: add missing description of -i option to usage text

[Alex Dowad]

I thought that BusyBox traceroute didn't allow the user to set the source
interface, and was searching all around for an alternative... until I
looked at the source and discovered it was there all along. This will
help other users to avoid making the same mistake.
