Ignored dotdirs are included in output file

### Description

Ignored (using the `--ignore` feature) dotdirs show up in the JSON output file.

### How To Reproduce

```
scancode -v --ignore ".*" --json-lines=scancode.json -l --strip-root .
```

no dotdirs show up in the verbose output (they are still analyzed based on subjective execution time), but they are included in the "scancode.json" file. Same behavior using explicit non-glob patterns, e.g. `--ignore ".venv"`.

### System configuration

* Linux
* scancode-toolkit 32.2.1
* rye (uv)
