Free all remaining objects in rb_objspace_free_objects

rb_objspace_call_finalizer didn't free fibers and neither did
rb_objspace_free_objects, which caused fibers to be reported as leaked
when using RUBY_FREE_AT_EXIT. This commit changes rb_objspace_free_objects
to free all remaining Ruby objects.
