Fix wrong PKGNAME and COMMENT when WITH_SASL is defined.
Please note that the openldap 2.2.x series is now considered obsolete
and is no longer maintained. Therefore, updates to this port would
be more conservative and less effort would be taken here in the future.
Current OpenLDAP users are encouraged to upgrade to 2.3.x.
