refactor(fs): use scope from tauri core (#825)

* fix(fs): scope checks on Android

On Android, when we call canonicalize() on "/data/user/0/appid" (which is the data dir), the result is a "/data/data/appid" path, so we need to adjust our scope for that.

* use scope from core

* update persisted-scope

* fix build

* dev branch
