Try to stabilize tst_qwidget_qwindow::tst_resize_count on X11

This test fails sporadically on OpenSUSE, with the widget receiving
multiple resize events. Assuming that window management kicks in at
unpredictable moments and changes the geometry of the managed widget
possibly in several steps, we try to turn off all window management
on X11.
