haskell-cuda: jump through hoops to make this build succeed

The package has undeclared dependencies on 'nvidia_x11' and 'cudatoolkit', the
latter of which also comes with a non-standard directory layout that our
builder cannot handle without help. Last but not least, the build hard-codes
impure search paths like /usr/local/cuda that need to be patched out.

Resolves https://github.com/NixOS/nixpkgs/issues/6562.
