Fix pipeline statistics test

The test calls glDrawRangeElements (mode=10, start=0, end=1, count=4, type=5125, indices=0x40)

But the index data is 0, 2, 1, 3

But a LINE adjacent primitive would use indices 2, 1 to make the line, now if the end == 1,
I don't think the behaviour for the first vertex is defined. If it gets clamped to 1,
you end up with a line 1,1 which our culling throws away as an empty line,
and we never run a fragment shader.

Now I think this is a bug in the test, in PipelineStatisticsQueryTestFunctionalBase::initVBO
m_vbo_n_indices = sizeof(raw_index_data_size) / sizeof(unsigned int);
