feat(nix/yants/tests): test drv type

Browse source 
By using an extremely trivial derivation we can ensure that it will not
throw if evaluated using deepSeq. When using stdenv.mkDerivation or
similar at some point something will most likely throw or generate some
kind of error which is alright in the context of nixpkgs, but makes
testing yants harder than you'd think it should be.
