Subject: [PATCH] superlu: fix darwin

The update from 5.2.1 -> 7.0.0 causes superlu segfaults running the
tests when linked with Accelerate due to superlu using the single
precision interface.  Set the Blas vendor to Generic to prevent cmake
from using Accelerate and use the nixpkgs provided blas/lapack
libraries.
