olcSyncprovConfig not converted for cn=config

[Oliver Liebel <oliver@itc.li>]

using openldap 2.4.14 (compiled from openldap.org source-package)
i have noticed the following, reproducable behaviour when converting
a slapd.conf to slapd.d:

olcSyncprovConfig is generated during conversion for the hdb-context, 
but not for cn=config,
although "overlay syncprov" is set for database config


tested the conversion several times with slaptest and slapd, with the
following simple example-slapd.conf. the result seems always to be the 
same.
