topotests: fix ignore routes with linkdown

Browse Source 
In topotest, a given interface has only the ignore routes bit turned
on for IPv6 only, whereas topotest is expected to turn it on for all
address families.

> # show interface
> Interface r2-r3-eth2 is up, line protocol is up
> [..]
>  flags: <UP,BROADCAST,RUNNING,MULTICAST>
>  Ignore all v6 routes with linkdown
>  Type: Ethernet
>  [..]

This is because the only the 'default' ipv6 ignore sysctl is set to
1. Set also the /proc/sys/net/conf/<family>/default/ignore_routes_with_linkdown
flag, to have same behaviour for ipv4 and ipv6.
