Subject: [PATCH] openblas: re-enable AVX512 support

AVX512 support was disabled due to an issue in the AVX512 DGEMM
kernel:

https://github.com/NixOS/nixpkgs/issues/59708

However, this kernel has been replaced upstream a while ago:

https://github.com/xianyi/OpenBLAS/releases/tag/v0.3.8

And they have enabled AVX512 kernels since then.
