elua: allow building with interpreted (non-luajit) lua

This doesn't fully work yet as e.g. Eolian bindings require
the bitop module only present in luajit for now.

In order to build, you will need to install

https://github.com/q66/cffi-lua

in order to provide the FFI. It needs to be built for the Lua
version you are building EFL with.
