selftests: forwarding: Specify interface when invoking mausezahn

Specify the interface through which packets should be transmitted so

Fixes: cab14d1087d9 ("selftests: Add version of router_multipath.sh using nexthop objects")
Fixes: 3d578d879517 ("selftests: forwarding: Test IPv4 weighted nexthops")
