Add new file 'debian-edu-router.ldif'. Empty proxy groups should be installed on all new Tjeners.

These are preconfigured empty proxy groups for the use in Debian Edu Router.
See Debian Edu Router Plugin: Content filter at https://salsa.debian.org/debian-edu/debian-edu-router/-/tree/master/docs.

share/debian-edu-config/gosa.conf.template: Activate nisNetgroup tab for user accounts.

This makes it possible to add a user into a nisNetgroup while editing a user.
This is a fine addition to the already present 'NIS Netgroup' tab on the left.

etc/dovecot/local.conf: Fix passdb block syntax for Dovecot 2.4.x compatibility.

Dovecot 2.4.x introduced a breaking change to the passdb/userdb
configuration block syntax. A prior commit 63523d4c partially adapted
etc/dovecot/local.conf to Dovecot 2.4.x by splitting mail_location
into mail_driver, mail_path, and mail_inbox_path, but did not update
the passdb block, leaving the configuration broken.

This causes Dovecot to fail immediately at startup with:
  - doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 10: passdb { }
  - dovecot.service: Main process exited, code=exited, status=89/n/a
