eina_list: Ensure single init

This fixes a crash in make check when --profile=dev is explicitely
enabled. eina_list_init() is called by the standard eina_init() loop
and by eina_debug_init() as well.

Honestly I'm not sure why it doesn't crash for other people as
well...

The crash was in eolian_suite during the second eina_init (called
from eolian_init).
