add patches to fix PyTorch 1.12 (CPU-only) w/ foss/2022a on POWER

[Flamefire]

(created using eb --new-pr)

This adds patches to fix failures when FBGEMM isn't used which AFAIK is only the case on PPC. In particular the forward-ported patch from #18489 and a new one due to a bug in a feature introduced in PyTorch 1.12.0
