Addition to the fix for BUG#9412 "Triggers: should have trigger privilege".

When we add new privilege we should update mysql-test/lib/init_db.sql
accordingly.


mysql-test/lib/init_db.sql:
  Added TRIGGER privilege.
sql/sql_acl.h:
  Updated comment describing process of addition of new privileges - added yet
  another script place which should be modified when new privilege is added.
