[pmg-devel] [PATCH pmg-api] debian/postinst: add old default values on upgrade to 8.x

[Dominik Csapak <d.csapak@proxmox.com>]

in /etc/pmg/pmg.conf for
advfilter
use_bayes
use_awl

Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>

we could use a little helper script, but the grep/sed lines look
harmless and easy enough to keep it here imho
