[Toybox] Problems with route command argument parsing

[Eduardas Meile]

Hello.

Perhaps you already know, but there are some issues with the pending 
route command argument parsing.

It seems this was noted quite some time ago on the mailing list:

http://lists.landley.net/htdig.cgi/toybox-landley.net/2017-August/009121.html

This is still not fixed in the latest toybox release 0.7.8 or on the 
master branch.

The suggestion provided actually does solve my problem of setting the 
default gateway, but probably this is not the only fix required.

If one tries setting the interface like in "route add default gw 
192.168.1.1 dev eth0", this won't get properly parsed either.
