Rudder

Since we do not have an automatic list of required packaged after #12117, we need to declare dependencies for rudder-slapd in rudder-inventory-ldap

This leads to the following error when restarting rudder-slapd:

installing libtool-ltdl fix the issue

We should add it as depedency of rudder-inventory-ldap (libltdl7 on sles systems)
