checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
The repository of the project has been transferred to a GitHub organisation.
See https://github.com/pure-fish/pure/issues/249.
The tests of this package are also failing upstream, so they have been
temporarily disabled here too.
