yq: fix path to jq

[ttuegel]

yq requires jq at runtime, so that the package is broken without patching in the path to jq.

Motivation for this change

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

if the package is "shelling" out to it, this should be patched in the source to do so. Otherwise there's no guarantee that it will work when imported as a python module.

[ttuegel]

Thanks for pointing that out! I patched the package; could you please take another look?

You can actually replace the variables you have with substitute within the patches declaration so you don't really need the postPatch for the JQ substitution.

Example:

nixpkgs/pkgs/applications/audio/curseradio/default.nix

Lines 20 to 25 in 14f2dc1

	patches = [
	(substituteAll {
	src = ./mpv.patch;
	inherit mpv;
	})
	];
