[pve-devel] [PATCH installer] fix postfix installation

[Stoiko Ivanov]

by:
* running /usr/bin/newaliases (generating /etc/aliases.db)
* setting the compatibility_level to 2
** otherwise a warning was issued with broken aliases.db that the system
   is using the backward compatible setting of $mydestination for $relay_domain
   (see [0]).

Tested by installing from ISO and creating a cronjob which runs 'echo test'
every minute.

Thanks to Martin for reporting this!
