selftests: net: use slowwait to make sure IPv6 setup finished

Sometimes the vxlan vnifiltering test failed on slow machines due to
network setup not finished. e.g.

  TEST: VM connectivity over vnifiltering vxlan (ipv4 default rdst)   [ OK ]
  TEST: VM connectivity over vnifiltering vxlan (ipv6 default rdst)   [FAIL]

Let's use slowwait to make sure the connection is finished.
