eo: Fix crash during eo_shutdown

I was getting a crash in eo_shutdown, inside
_efl_event_pointer_class_destructor as I was calling eo_del
from there. But the parent class was already destroyed.

Assuming class IDs can only go up, and child classes are only
instanciated after all their parents, it is safer to call the
class destructors in reverse order.

Obviously, still pretty sure eo_del() in a class_destructor
is not a good idea...
