arpack: add ISO C binding and top arpack-mpi attribute

[fedeinthemix]

I'd like to propose to enable the ISO C bindings which are used by some programs.

In addition, I'd like to add a top attribute arpack-mpi with MPI enabled. This makes it easier to use the arpack with MPI in flakes.

https://hydra.nixos.org/build/282505341 and the logs from this PR https://logs.ofborg.org/?key=nixos/nixpkgs.357259&attempt_id=19a3b55b-cc66-414d-a380-8c9dcd0456ad

it seems to add single precision api which Accelerate doesn't like so darwin needs to link with openblas.

not quite sure what the difference is before / after but looking at the unit tests run it is now running what looks like a single precision unit tests which segfaults where before this change it wasn't (only 6 tests vs 10).

we've seen this issue with other things using accelerate and single precision on darwin and the fix is simple. will have a PR up shortly.
