Motivation for this change

Implement stuff I learned at https://savannah.gnu.org/bugs/?57591#comment112 .

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Don't use `with stdenv.lib` at the top of the expression, per:
https://nix.dev/anti-patterns/language.html#with-attrset-expression

Use rec and version inside `mkDerivation`, like almost any other
derivation.
Do it before buildInputs per:
NixOS#94892 (comment)

Remove unneed, BLAS_LIBS and LAPACK_LIBS from environment - the
libraries are detected just fine when in buildInputs.
