As reported by Andy, kernel-doc.py is creating a __pycache__
directory at build time.

Disable creation of __pycache__ for the libraries used by
kernel-doc.py, when excecuted via the build system or via
scripts/find-unused-docs.sh.

Reported-by: Andy Shevchenko <andriy.shevchenko@intel.com>
Closes: https://lore.kernel.org/linux-doc/Z_zYXAJcTD-c3xTe@black.fi.intel.com/
