Bug#1108933: pdns: Please drop init.d upgrade code

[Chris Hofstädtler]

Source: pdns
Version: 4.9.4-2
Severity: normal

Note to self:

Upstream will drop the upgrade code for old init.d installs in the 
next release. We should also drop it - basically delete 
pdns-server.preinst.

Recursor already did this for trixie!
