Subject: [PATCH] Use the correct path when checking if a `/l10n` directory
 exists, to avoid errors during `gulp importl10n` (PR 7063 followup)

This is regression from PR 7063, causing `gulp importl10n` to fail:
```
$ gulp importl10n
[19:45:02] Using gulpfile c:\Users\Jonas\Git\pdfjs\gulpfile.js
[19:45:02] Starting 'importl10n'...

Downloading ach...
