Eolian CXX: Remove unneeded Eo.h include.

Eo.h depends on things that are generated by normal Eolian, and because Eolian C++
is generating code pre-build (WHY THE FUCK???), the dependencies are missing.

This removes the stupid include, but a more proper fix would be to move eolian_cxx
to be part of the build process and not pre-build.
