Turbopack: fix route format for NFT globs (#82997)
These are effectively the tests for https://github.com/vercel/next.js/pull/82906
`outputFileTracingIncludes` and `outputFileTracingExcludes` match not against the pathname of the routes, but also include the app/pages prefix, e.g. `app/route1` for `src/app/route1/route.js` (at least the Webpack implementation does, which is what we're replicating here).
