Building against Python 3.12 is broken

[dogtopus]

Describe the bug

Python 3.12.0 has a bug (python/cpython#106560) that will cause the compilation of pm3 client to fail.

A workaround would simply be disabling -Werror for redundant-decls.

To Reproduce
Steps to reproduce the behavior:

1. Build proxmark3 client with Python 3.12.0
2. See it fail with -Werror=redundant-decls

Expected behavior
Build under Python 3.12.0 successfully.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Fedora 39
• inside proxmark3 client run the following commands and paste the output here.
• hw version
• hw status
• data tune

Additional context
Add any other context about the problem here.

Does the cmake work?

@wh201906 Presumably no since it's a Python issue, unless CMake didn't honor -Werror by default for some reason.

[wh201906]

I don't have Fedora 39 so I did a test roughly and it seems to only affect the make command. Could you please help me to test cmake on Fedora 39 with Python 3.12?
As for the Makefile, I've made PR #2185 to fix it.

@wh201906 I tested using cmake on Fedora 39 and it builds fine. Thanks a lot.

[iceman1001]

merged the fix.
