If the Script-and-Regex linter captures no "line" text, treat the message as affecting the entire file

Browse source 
Summary: Fixes T10124.

Test Plan:
Added this "linter" to `.arclint`:

```
    "thing": {
      "type": "script-and-regex",
      "script-and-regex.script": "echo every file is very bad #",
      "script-and-regex.regex": "/^(?P<message>.*)/"
    }
```

...to produce this diff. Also made a variant of it which matches lines to make sure that still works.
