TestCase::mouseDrag: set mouse move delay >= 1 ms

Infinite-speed drags do not work well with velocity-sensitive
components like Flickable.  As with change d04982dc on qtbase,
adding a short delay helps to stabilize tests.

To keep it flexible, we make QTest::defaultMouseDelay()
available via the qtest_events.defaultMouseDelay property.
So the delay can be increased by passing a larger delay
value to mouseDrag, or by changing the QTEST_MOUSEEVENT_DELAY
environment variable (as before).
