DYNDNS: support for dualstack

When dyndns_iface option was not used, address of connection to LDAP
was used. This patch proposes following change:
  * Interface containing address of connection is found.
  * All A and AAAA addresses of this interface are collected.
  * Collected addresses are sent during DDNS update.
  * Function sss_iface_addr_add() is removed.
