net: enable tcp backlog by default

Browse source 
If the NET_TCPBACKLOG configuration is not enabled, no I/O event will be
triggered for the socket file descriptor in poll/epoll. As a result, the
connection will not be accepted, leading to a failure in the TCP handshake.

The problem is that users may not have noticed this configuration,
no event will be received when polling the socket fd.
