Nix: Get the Nix shell working on macOS/aarch64.

Browse Source 
Improvements to the Nix configuration so that macOS is supported.

Microsoft SQL Server is still not supported (yet; I have something in mind there), but the rest works. You can still use Homebrew to install the SQL Server drivers.

I had to make the following changes:

* I updated nixpkgs, because it's been a while.

* I made `ODBCINSTINI` optional so that it's not loaded on macOS, as it depends on `msodbcsql17`, which is broken on macOS.

* I upgraded OpenSSL.

* I set `DYLD_LIBRARY_PATH` on macOS so GHC finds OpenSSL; otherwise, it uses the wrong version of `libcrypto`, and fails with a fun error:

  > WARNING: ghc is loading libcrypto in an unsafe way

* I patched GHC to fix compilation on macOS (copied from https://github.com/NixOS/nixpkgs/pull/149942).

To test this out, you can run `nix develop` (or install [direnv][] and add `use flake` to _.envrc.local_), and then try building HGE in the shell provided.

Fair warning: GHC needs to be built, and takes _aaages_ the first time. If this becomes useful to others, we can set up a shared cache.
