lwtunnel: autoload of lwt modules
The lwt implementations using net devices can autoload using the existing mechanism using IFLA_INFO_KIND. However, there's no mechanism that lwt modules not using net devices can use. Therefore, add the ability to autoload modules registering lwt operations for lwt implementations not using a net device so that users don't have to manually load the modules. Only users with the CAP_NET_ADMIN capability can cause modules to be loaded, which is ensured by rtnetlink_rcv_msg rejecting non-RTM_GETxxx messages for users without this capability, and by lwtunnel_build_state not being called in response to RTM_GETxxx messages.
