The OpenLDAP license is versioned. As such, listing the license as
simply "OpenLDAP" does not convey a complete picture of what license the
component is actually using.
Update the LICENSE variable to use the SPDX identifier for OpenLDAP
licenses, with the appropriate version number, "OLDAP-2.8".
Rename the license file for the OpenLDAP license to "OLDAP-2.8" from
"OpenLDAP".
