package/python-pyqt5: disable qt5webkit module

Due to issues in the installation of qt5webkit, building the
corresponding Python binding fails:

Project ERROR: Unknown module(s) in QT: webkit
Error: /home/thomas/buildroot/br/output-all/host/bin/qmake failed to create a
makefile from PyQt5.pro.
make[1]: *** [package/pkg-generic.mk:263: /home/thomas/buildroot/br/output-all/build/python-pyqt5-5.15.6/.stamp_configured] Error 1
make: *** [Makefile:83: _all] Error 2

was an attempt at fixing it, but this patch doesn't work and looks
weird.

So for the time being, disable the Webkit module in python-pyqt5. This
issue has indeed been around for as far as 2022.
