fix: only eval enable option if visible

[zimbatm]

When using lib.mkRenamedOptionModule, the trace warning is emitted whenever the option is accessed.

Because we iterate and check the .enable option of all the programs, the renamed option gets accessed all the time.

So we check if the option is "visible" before checking in, which lib.mkRenamedOptionModule sets to false.

Fixes #211

I've tried it with

nix-info

$ nix-shell -p nix-info --run "nix-info -m"
 - system: `"x86_64-linux"`
 - host os: `Linux 6.6.44, NixOS, 24.11 (Vicuna), 24.11.20240809.5e0ca22`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.18.5`
 - channels(root): `"nixos"`
 - nixpkgs: `/nix/store/0jr2kk95c34c0b6yxi75q4fqgb43kqkm-source`
