Support building against OpenLDAP 2.6+

OpenLDAP 2.6 deprecated separate libldap/libldap_r, there is only one
(reentrant) variant for the library.

Attempt to use _r variant by default. In case it is missing, assume we
are using OpenLDAP 2.6 which has libraries without _r suffix. The
functions are still reentrant so there is not functional difference.
