nixos: bump codex-desktop-linux to build-info no-shadow fix

Point the codex-desktop-linux input at colonelpanic/linux-build-info-no-shadow
(PR ilysenko/codex-desktop-linux#438), which carries the merged build-info
settings work plus the fix preventing injected helper locals from shadowing
minified bundle bindings.
