lodbias: Reduce the number of glReadPixels calls

Nanley Chery requested to merge nchery/piglit:faster-lodbias into master

Read the framebuffer once per probe_cell call instead of doing so 16 times. With debug builds of piglit (GBM platform) and iris, this change improves the runtime of the test on a TGL by about 12x and allows it to run in the CI without timing out.

The CI timeout issue was reported by @craftyguy.
