rust-filepatterns: match exact `rootglob`s with a `HashSet`, not in the regex

This optimization yields some very interesting results in `rootglob`-heavy
repositories.

I build a test repository of the following structure:

```
root
    /<uuid>/build/empty_file
    ... repeat for 4000 entries
```

and a `.hgignore` containing the corresponding 4000 `rootglob` entries pointing
to all `build/` folders.

Rust+c `hg status` goes from 350ms down to 110ms.
