OSX: avoid crash in invalidateBuffer_resizeHelper on parentless widget
KDE4 has a KMenu::addTitle function that adds a distinctive item to
a menu, as the predecessor to Qt5's QMenu::addSection. On OS X this
function leads to a null pointer access because
invalidateBuffer_resizeHelper is called on a parentless widget.
This patch filters out such widgets.
Task-number: QTBUG-41716
