fix(overrides): Don't warn on duplicate packages from using '..'

### What does this PR try to resolve?

As part of #10752, I was changing the "duplicate package" warning to be like:
```
[WARNING] skipping duplicate package `a2 v0.5.0 ([ROOT]/foo/b/../a)`:
  [ROOT]/foo/b/../a/a2/Cargo.toml
in favor of [ROOT]/foo/a/a2/Cargo.toml
```
and it showed that we were considering two paths to the same package to be duplicates.

This suppresses that warning.

### How should we test and review this PR?
