Revert "Drop debian/debian-edu-config.preinst obsolete since buster...

  * Drop share/debian-edu-config/tools/password-fix-squeeze-r0 for the same

    reason.

  * Drop stuff commented out in 2012 in ldap-bootstrap/root.ldif.

  * Drop debian/debian-edu-config.preinst obsolete since buster development

    had begun.
