(ITS#5355) back-meta calls back-ldap directly

back-meta currently makes direct calls to back-ldap. The specific way in which this caused problems is that Debian uses a patched libltdl (to deal with other problems unrelated to OpenLDAP) across the whole distribution which does not open modules with the RTDL_GLOBAL flag and hence doesn't populate all functions into the global namespace. However, my understanding is that regardless of the merits of that particular decision, the current linkage between back-meta and back-ldap is against OpenLDAP's module policy and it's something that you would want to correct.
