Attempt to make the positioning test of QWindow more reliable

The part of the test that verifies that setFramePosition moves the window
successfully appears to be very unreliable in the CI system. The "tested"
frame position is calculated to be at (40, 40) relative to the top left
of the available screen geometry, which can be non-zero due to task bars
and similar system ui elements. However that position appears to be
unreliable in the sense that the window manager doesn't seem to always
respect that. So instead let's try placing the window (by frame position)
in the center of the screen instead.
