Building of QWaylandIntegration fails if some Qt5 features are disabled

QPlatformIntegration's interface methods are disabled based on QT_NO_OPENGL, QT_NO_CLIPBOARD, QT_NO_DRAGANDDROP, QT_NO_ACCESSIBILITY and QT_NO_SESSIONMANAGER.

These has to be taken into account when compiling QtWayland.

Problem is evident when trying to compile QtWayland with Yocto/meta-qt5's default settings.
