Add SO_PASSRIGHTS constant to socket module

Feature or enhancement

Proposal:

Linux recently added support to SO_PASSRIGHTS, to prevent unix sockets from receiving file descriptors.

Python should have this constant to be able to use it with setsockopt.

import socket
socket.SO_PASSRIGHTS

Has this already been discussed elsewhere?

首先檢查 Python 的 socket 模組如何公開平台 socket 常數，以及 setsockopt 如何使用這些常數。查看已連結的 PR gh-135355，了解已在進行的工作。當 socket.SO_PASSRIGHTS 可在支援的 Linux 系統上與 setsockopt 一起使用時，即視為完成。
