Subject: Adapt to nixpkgs' nativeCheckInputs change
X-Git-Url: http://git.scottworley.com/auto-upgrade-with-pinch/commitdiff_plain/567ba6eb5941408322eaf704af3dacbb51fd9f0d?hp=c418324b4fa5ebf5046d623548e04e74d128f3d1

Adapt to nixpkgs' nativeCheckInputs change

nixpkgs commit f39abbc3500451fc00c80fed71b0f6f7bba8b6a4, first released in
23.05, requires that everyone move their checkInputs to nativeCheckInputs.
To build both before and after this change, we detect whether we're before
or after this change by reading the manual & behave appropriately.  :/
