    lua-factory: _load_goa_data() only if goa is available
    
    Let's wrap grl_lua_library_load_goa_data() to be build only if
    GOA_ENABLED is declared, otherwise we will get -Wunused-function
    
      grl-lua-library.c:1746:1: warning: ‘grl_lua_library_load_goa_data’
      defined but not used [-Wunused-function]
    
    It is also worth to mention that grl_lua_factory_add_goa_source() in
    grl-lua-factory.c is already wrapped this way.
