tests: make exposeEventOnShrink_QTBUG54040 not flakey on xcb
From: https://tronche.com/gui/x/xlib/events/exposure/expose.html
"The circumstances in which the X server generates Expose events
are not as definite as those for other events."
On windows with XCB_GRAVITY_NORTH_WEST flag set we should not get
expose events according to e2665600c09358854bb0b29389cc873a2684f77b,
but as stated earlier this might not always be true.
Nevertheless, sometimes we get expose event from X server when shrinking
window, but most of the time we don't. Make the test not flakey by
checking that we get at least 1 expose event, instead of exactly 1.
Now running test 500 times in a loop does not fail.
Task-number: QTBUG-63424
