Require gateways for routes to be of the same address family as the
route itself.

It fixes a bug where an IPv4 route for example has an IPv6 gateway
specified:

     route add 10.1.1.1 -inet6 fe80::1%fxp0

     Destination  Gateway       Flags  Refs  Use  Netif Expire
     10.1.1.1     fe80::1%fxp0  UGHS   0     0    fxp0

The fix rejects these illegal combinations:

     route: writing to routing socket: Invalid argument
     add host 10.1.1.1: gateway fe80::1%fxp0: Invalid argument
