some cc don't like the way cython use EINA_LOG macros

In some system we saw the compilation fail with this error:
efl/eo/efl.eo.c:1137:60: error: format not a string literal and no format arguments [-Werror=format-security]
   EINA_LOG_DOM_INFO(__pyx_v_3efl_2eo_PY_EFL_EO_LOG_DOMAIN, __pyx_k_Initializing_efl_eo);

so just ignore those warnings
