If you can guarantee us that the name of the folder we would need to 
delete is always /var/backups/unknown-2.4.44+dfsg-5+deb9u1.ldapdb -even 
in future package updates- that is a possibility.
However would prefer not to make assumptions like that :-)

It is respecting it for the destination of the database dump.
But in addition to making a database dump, it also wants to move the 
original folder to /var/backups, and I do not see any option to change 
that destination.

==
# echo "slapd slapd/dump_database_destdir string 
/var/backups/just-testing" | debconf-set-selections
# DEBIAN_FRONTEND=noninteractive dpkg-reconfigure slapd
   Backing up /etc/ldap/slapd.d in /var/backups/just-testing... done.
   Moving old database directory to /var/backups:

   Backup path /var/backups/unknown-2.4.44+dfsg-5+deb9u1.ldapdb exists. 
Giving up...
