The existing nlohmann_json expression prevents users from overriding
fields (like `doCheck`) because it uses `rec` in the argument to
`mkDerivation`. Let's use the shiny new
pass-a-function-to-`mkDerivation` feature to do the same thing without
blocking overrides.

`cmake` should be in `nativeBuildInputs` as it is only required at build time. For obvious reasons we can't have the tests running during a cross-compile. I figured I'd update the package version while I was at it, though these changes have also been tested independently of the version update.
