Fix tst_qquickpath not to use fuzzy compare

On arm platforms, qreal == float. QPointF stores its coordinates internally on
qreal variables (float on arm). When QPointF comparison takes place, a call to
qFuzzyIsNull(float) will ultimately be triggered, causing the test to fail for
some values, because the epsilon of 0.00001f is too small.

In the particular case regarding BB10, the comparison between QPointF(100,
150) and QPointF(99.9999771, 150) is failing because of that.
