attribute 'buildInputs' is missing

[krscott]

I am using this method wrap binaries. #152 broke my config, giving the error below. I was able to fix the error using (oldAttrs.buildInputs or []). I'm guessing the attribute is missing due to my non-standard usage, though I'm relatively new to nix so I admit I don't fully understand the underlying issue. I'll submit my fix as a PR, but I'm open to alternative solutions.

Looks like this is addressed by pending PR #165 already
