Turbopack: fix duplicate facade module (#78191)
Previously, the `[project]/turbopack/crates/turbopack-tests/tests/execution/turbopack/side-effects-optimization/basic/input/node_modules/tla/tla-reexported.js [test] (ecmascript) <export tlaReexported as tlaReexported2>` module was duplicated.
A regression from https://github.com/vercel/next.js/pull/73544
In all of these synthetic modules reexporting modules, the AST isn't actually needed.
