package/python-pybind: overwrite 'pybind11/_version.py' with a hard-coded version

Browse Source 
Fixes build error with python-pillow since its version bump to 12.0.0
which introduced a dependency to pybind with buildroot commit
5f446a8d6d:

FileNotFoundError: [Errno 2] No such file or directory:
 '/home/bernd/buildroot/output/host/lib/python3.13/site-packages/include/pybind11/detail/common.h'

Implement the solution suggested by Vincent Fazio [1]:
Generate `pybind11/_version.py` file with a hard-coded version to avoid
copying pybind11 headers in HOST_DIR.
