lx: lx_netlink_getroute ipv6 support would be nice

[wiedi]

Newer linux distributions no longer ship with netstat. And while netstat -rn6 worked to display the IPv6 routing table the supposed alternative ip -6 route show only results in:

Cannot send dump request: Protocol error

The reason seems to be that the netlink method is simply not implemented yet: https://github.com/joyent/illumos-joyent/blob/4f5bbb4c37e2dca7b0722f89c8dfe13be1fbc131/usr/src/uts/common/brand/lx/io/lx_netlink.c#L1477

And while /native/usr/bin/netstat -rn works for now proper support would be nice. Thanks! :)
