    ve/net: sit: enable in container
    
    Currently we fail to create sit interface inside container,
    because it have neither NETIF_F_VIRTUAL nor NETIF_F_NETNS_LOCAL:
    
      ipip6_tunnel_ioctl
       ipip6_tunnel_locate
        ipip6_tunnel_create
         register_netdevice
          ve_is_dev_movable
    
    Mark sit as NETIF_F_VIRTUAL to fix this issue.
