busybox: ifupdown:pass interface device name for ipv6 route command 

IPv6 routes need the device argument for link-local routes, or they
cannot be used at all. E.g. "gateway fe80::def" seems to be used in
some places, but kernel refuses to insert the route unless device
name is explicitly specified in the route addition.
