net: add __sys_socket_file()
This works like __sys_socket(), except instead of allocating and
returning a socket fd, it just returns the file associated with the
socket. No fd is installed into the process file table.
This is similar to do_accept(), and allows io_uring to use this without
instantiating a file descriptor in the process file table.
