XCB: Always set X window attributes in QXcbWindow::setWindowFlags().

Browse Source 
QDockWidget and QToolBar set the Qt::BypassWindowManagerHint window flag
when unplugging and clear it in the endDrag() methods. This does not have
any effect since the attribute is not taken into account in
QXcbWindow::setWindowFlags(). Change the method to always set the attributes,
which should also make it possible to set/clear Qt::WindowTransparentForInput.
