Since the test was refactored and QCursor::setPosition() replaced
with QTest::mouseMove(), the test is completely crippled on macOS,
since it relies on the parts in widget's code, ifdefed with condition
!Q_OS_OSX and commented as "Cocoa tracks popups". Yes it does,
but not for "fake" events generated by QTest. The original test
was introduced when fixing different problems on non-Apple platform(s)
anyway. Let's make QSKIP message saying the truth.
