package/libdnet: drop support for Python module

The libdnet Python module no longer builds with Python >= 3.13. The
issue has been reported upstream on August 17, 2025, and there has
been no feedback:

  https://github.com/ofalk/libdnet/issues/114

Until this gets resolved, we have no choice but to drop support for
the Python module of this package.

Fixes:
