Do not make extracted output directories read-only #680
Description
b6295dd made extracted output directories read-only. As explained in the commit, the intent was to communicate that this directory should not be modified manually. While this makes sense, making the directory read-only also has the side effect that users can't remove the directory at all after running trust extract without root privileges, which is suboptimal. Please make the directories writable again so that unprivileged users can remove extracted output directories owned by the user.
