Whitelist internal bookmarks manager for chrome_settings_overrides manifest key

Allow the Chrome-internal bookmarks manager extensions to specify
the chrome_settings_overrides manifest key in all channels, so that
they can use the bookmarks_ui subkey. Specifying subkey channels in
manifest_features.json would be better, but this is not fully supported
yet.
