tcp, tcp_splice: Fix port remapping for inbound, spliced connections
In pasta mode, when we receive a new inbound connection, we need to select a socket that was created in the namespace to proceed and connect() it to its final destination. The existing condition might pick a wrong socket, though, if the destination port is remapped, because we'll check the bitmap of inbound ports using the remapped port (stored in the epoll reference) as index, and not the original port. Instead of using the port bitmap for this purpose, store this information in the epoll reference itself, by adding a new 'outbound' bit, that's set if the listening socket was created the namespace, and unset otherwise. Then, use this bit to pick a socket on the right side.
