[net PATCH 2/2] selftests: forwarding: local_termination: sleep before starting tests

[Christian Marangi]

It seems real hardware requires some time to stabilize and actually
works after an 'ip link up'. This is not the case for veth as everything
is simulated but this is a requirement for real hardware to permit
receiving packet.

Without this the very fist test for unicast always fails on real
hardware. With the introduced sleep of one second after mc_route_prepare,
the test corretly pass as the packet can correctly be delivered.
