Remove olcBackend={0}hdb.ldif

[ebourg]

Another issue spotted while converting from HDB on Debian 11 to MDB on Debian 12, I had to remove manually /etc/ldap/slapd.d/cn=config/olcBackend={0}hdb.ldif after running the script. On Debian 12 this file prevents slapd from starting.

dn: olcBackend={0}hdb
objectClass: olcBackendConfig
olcBackend: {0}hdb
structuralObjectClass: olcBackendConfig
entryUUID: 486c82f2-5217-1030-9e09-09781a3cc679

humm, in the script we moved olcDatabase={1}hdb.ldif perhaps our ldap history

can you test this patch :

I can no longer test but it looks good.
