Motivation for the change, related issues

Related to #2993

Because of the Emscripten upgrade from 4.0.5 to 4.0.19, a new file appeared when running the virtual filesystem. Mostly invisible until I mounted a directory. This pull request disables the profiling data generated file.

Implementation details

• Add a root/replace in base-image Dockerfile.
• Add a test in filesystems.spec.ts
