package/openldap: security bump to version 2.4.56

Fixes the following security issue:

- CVE-2020-25692: A NULL pointer dereference was found in OpenLDAP server
  and was fixed in openldap 2.4.55, during a request for renaming RDNs.  An
  unauthenticated attacker could remotely crash the slapd process by sending
  a specially crafted request, causing a Denial of Service.
