[issue38692] add a pidfd child process watcher

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

As I already proposed previously, I proposed PR 17290 to simply skip test_pidfd_open() if os.pidfd_open() fails with a PermissionError.

I don't propose to change os.pidfd_open(), only the test unit for practical reasons: not bother users who have to use a strict Linux sandbox using a syscalls whitelist.
