Tracing fails to detect fs when used in multiple entries with webpack 5

[ijjk]

Continuation of #185

When building a Next.js project that reads from the filesystem in multiple pages the webpack output changes and nft fails to detect the needed local files. When only one page reads from the filesystem the webpack output is handled correctly.

Related Next.js issue: vercel/next.js#24700
Provided Next.js reproduction: https://github.com/jacksonhardaker/next-webpack-5-fs-bug

Example output when only one page reads from the filesystem (traces `/data` correctly)
