ada: Fix checking of Refined_State with nested package renamings

When collecting package state declared in package body, we should only
recursively examine the visible part of nested packages while ignoring other
entities related to packages (e.g. package bodies or package renamings).

gcc/ada/

	* sem_util.adb (Collect_Visible_States): Ignore package renamings.
