eina: fix compilation if safety checks are disabled

eina: fix compilation if safety checks are disabled

A few files include eina_safety_checks.h and then expect that
eina_log.h is also dragged in, however this isn't the case if
the safety checks were disabled at configure stage.

Include eina_log.h explicitly to fix this.
