SCons: Don't attempt to resolve paths in emitter

[Repiteo]

(probably) Resolves #104851 (comment)

This turned out to be a redundant step, as the path was already passed as absolute beforehand. Removing it keeps the path as absolute, without attempting symlink resolution.

[Ivorforce]

I tried this branch, by symlinking thirdparty/embree/common elsewhere (in hopes that it somewhat truthfully represents the issue being addressed). I'm getting this error:

Oh, it thinks it has a file instead of a directory? I think that's a separate issue entirely, but I guess I can more broadly look into how SCons treats symlinks as a whole
