efl/emotion: refactor init/shutdown, load modules from eina_prefix.

* emotion_init() and emotion_shutdown() now exist, let's do our
   initialization from there.

 * smart_add/smart_free will call init/shutdown for legacy apps.

 * use eina_prefix to determine runtime location.

 * use eina_module_arch_list_get()
