[Devel] [PATCH RH7/RH8] ve/net: sit: enable in container

[Vasily Averin]

Currently, we fail to create sit interface inside container,
because it has 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.
