This fixes a bug where unveiling a subdirectory of an already unveiled path would sometimes be allowed and sometimes not (depending on what other unveil calls have been made). Now, it is always allowed to unveil a subdirectory of an already unveiled directory, even if it has higher permissions. This removes the need for the permissions_inherited_from_root flag in UnveilMetadata, so it has been removed.
