darling: disable build on hydra

[ghpzin]

Description of changes

• disable build on hydra

Since at least version unstable-2023-11-07 (after 2023-11-25) builds on hydra fail with "Output limit exceeded":
https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.darling.x86_64-linux
https://hydra.nixos.org/build/242152891

src size (3512428168) is beyond current hydra limit (3421225472):
