python39: updated to 3.9.4

Python 3.9.4

Core and Builtins
bpo-43710: Reverted the fix for https://bugs.python.org/issue42500 as it changed \ 
the PyThreadState struct size and broke the 3.9.x ABI in the 3.9.3 release \ 
(visible on 32-bit platforms using binaries compiled using an earlier version of \ 
Python 3.9.x headers).

Library
bpo-26053: Fixed bug where the pdb interactive run command echoed the args from \ 
the shell command line, even if those have been overridden at the pdb prompt.
