Before

```bash
$ maturin sdist -m ~/Desktop/ruff/ruff_cli/Cargo.toml -o dist
💥 maturin failed
  Caused by: No such file or directory (os error 2)
```

After

```bash
$ maturin sdist -m ~/Desktop/ruff/ruff_cli/Cargo.toml -o dist
💥 maturin failed
  Caused by: failed to normalize path `/Users/messense/Desktop/ruff/ruff_cli/Cargo.toml`
  Caused by: No such file or directory (os error 2)
```
