Fix missing dependency on x11/qt6/qtquick3d

aja detects that x11/kde-plasma/kactivitymanagerd cannot be built.

If we look at the CMake trace, we see that KF6Config depends on QML,
which is registered as a lib dependency in KF6Config.

But it looks like KF6Config OR x11/qt6/qtdeclarative depends on
x11/qt6/qtquick3d in the cmake files. This still needs to be
investigated in detail. This diff fixes the faulty trace, but can
probably also occur in other configurations

OK?
