modules/checkers: stop setting til_frame_plan_t.cpu_affinity
In the early days of checkers when I introduced fill_module= with the per-cpu contexts to still allow threaded rendering, the whole seed passing to contexts thing wasn't as well sorted out. This meant the contexts often produced vastly different outputs despite being the same module, same seed, and same settings. The consequence of that was that w/fill_module checkers would produce crazy randomized output when you expected the same output in the filled cells. But by using .cpu_affinity (which I had to implement just for this use case actually) at least the different outputs would become stable. It was a band-aid over a different problem that still needed sorting out. Nowadays, it seems like this is improved enough at least for alphazed to look correct without the affinity hack, so I'm removing it because it really kills checkers threaded performance. Whatever modules remain uncooperative WRT seed reproducibility, they'll just need to be fixed up.
