$NetBSD: patch-Lib_test_test__shutil.py,v 1.1 2023/11/10 09:48:40 nia Exp $

posix.copyfile does not exist on Tiger. 

Python 3.8's posix._fcopyfile implementation unconditionally uses <copyfile.h>, 
which only exists on Leopard ane newer. This patch removes posix._fcopyfile 
on Tiger - this is okay because the rest of the stdlib uses posix._fcopyfile 
only conditionally after checking that the function exists 
(non-Apple systems don't have posix._fcopyfile either).
