s4-ldb: allow for unescaped '=' in a index DN
The ldb_dn_explode code normally enforces all special characters,
including a '=', must be escaped. Unfortunately this conflicts with
the ltdb index DNs, which for binary attributes may be base64
encoded. This allows a unescaped '=' as a special case for index DNs.
