Currently, we fail to init ipip per-net in a ve, because it has neither
NETIF_F_VIRTUAL nor NETIF_F_NETNS_LOCAL:
ipip_init_net
ip_tunnel_init_net
__ip_tunnel_create
register_netdevice
ve_is_dev_movable
In PCS6 ipip has NETIF_F_NETNS_LOCAL, so everything works fine there,
but this restriction was removed in RH7 kernel, so we fail to start a
container if ipip is loaded (or load ipip if there are containers
running).
Mark ipip as NETIF_F_VIRTUAL to fix this issue.
