Add SO_PASSRIGHTS constant to socket module

[ltworf]

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

The 6.16 kernel now goes into the stabilization period, with the final release expected July 27 or August 3.
