As discussed in https://github.com/SELinuxProject/selinux/issues/64, semodule_deps has apparently been broken for a very long time for binary modules and is completely irrelevant for CIL modules. If there are any users of it, they ought to be rewritten anyway since it is not producing correct dependency information, and the ultimate goal is to stop using binary modules altogether so it is not worth fixing. Remove it to avoid any further broken usage.
