dateMenu: Set _delegate on non-menu-item menu child

PopupMenu needs special-treatment of certain types of menu items,
which it determines via children's _delegate property. However as
the calendar drop-down is very unmenu-ish, we use regular actors
rather than PopupMenuItems and the missing _delegate property
triggers a warning. Just add it as the bare minimum to make
PopupMenu happy.
