dev-python/pyqt6: fix build with Qt 6.12

Early fix, could potentially break again. Not particularly tested
but seems to work at least to run qutebrowser with it.

Not overly worried given Qt 6.12.0 will be masked like usual and
odds are there will be a pyqt6-6.12.0 relesed before we add 6.12.1
unmasked.
