Fixed autotest failures in tst_QPainterPath.

The simplified test failed because the ellipse was flattened into line
segment. The other tests were due to a behavioral change in contains()
and intersect() caused by using fill based intersection in change
f7d61dab69308f0993c8a5f2232226d1713ac4a7. This needs to be reverted,
since it will return false for a rect containing a line (with no fill
area). Instead a different fix was needed in linesIntersect() to prevent
testIntersections() in tst_QPathClipper from failing.
