efl_net_dialer_socket: allow us to create a dialer from existing object.

If we want to upgrade a dialer, then we must have a way to know if
that socket has already adopted another socket so we don't create it.

We can't simply use efl_net_socket_ssl, otherwise we'd miss some
methods such as efl_net_dialer_address_dial_get() and events such as
connected.
