Subject: [PATCH] fex: use packaging for aarch64_fit_native.py

The build's Python env only provided setuptools for the pkg_resources fallback
in Scripts/aarch64_fit_native.py, but modern setuptools / Python 3.14 no longer
ship pkg_resources and packaging was never added, so configure aborted at
string(STRIP ...) (CMakeLists.txt:494). Use packaging, which the script prefers;
libclang (thunk generator) is unchanged.

Assisted-by: Claude Code (Claude Opus 4.8)
