[Piglit] Faster piglit with probe_rect_*

[Marek Olšák]

Hi,

I've optimized piglit by reducing the number of glReadPixels calls in tests
which probe from hundreds to hundreds of thousands of pixels (the fbo tests
are the worst ones). It touches shader_runner and 26 other tests. The
quick-driver.tests profile is significantly faster now (especially for GPUs
which store framebuffers in VRAM). If there are no concerns, I'll merge this
on thursday evening CEST.
