openblas: 0.3.4 -> 0.3.5, rework a bit (#53972)

* openblas: simplify a bit, fix doCheck so tests are enabled non-cross.

* doCheck should be 'true' in (at least) the non-cross case,
  this looks like an inverted check that's largely benign
* doCheck will be set to 'false' in the cross case anyway,
  makeDerivation does this IIRC
* targetPrefix can be used without checking, probably by design

Derivation hash does change but no "real" functionality change intended.

* openblas: nix types for config attrs (hash-preserving)

* openblas: more nix-ification, merge in cross attrs, prefer to always set

(but set appropriately for cross and non-cross cases both)

* I'm not sure what NO_BINARY_MODE does,
  this change now sets explicitly false in the non-cross scenario
  (previously unset unless cross).
* Drop musl NO_AFFINITY case, will be removed in upgrade shortly

* openblas: 0.3.4 -> 0.3.5
