Set frameless window hints on QGL test windows under QWS

QWS combines the window title bar and the top-level widget
into one window surface, which causes problems when the top-level
widget is a QGLWidget: the raw GL surface contents are not the
same as on other platforms where only the top-level widget
contents are included in the window surface.

This change sets Qt::FramelessWindowHint on QWS systems on
widgets where we need to read back the top-level widget for
comparison against a reference image.
