macosx: Remove teletext case from MainMenu validation

It seems the teletext menu item validation special case is not
necessary at all anymore.
If the parent item is disabled, it does not seem to matter if the
subitems are enabled or not, as access to the subitems is not possible
when the parent is disabled.
