[pve-devel] [PATCH installer] install: set timezone, before configuring postfix

[pve-devel] [PATCH installer] install: set timezone, before configuring postfix

[Stoiko Ivanov]

quite a few changes have been made to the postfix package in trixie.
one of those is that `configure-instance.sh`, which handles
chroot-creation is now called on service startup and e.g. with
`postfix check`, which we run here[0].

this results in /etc/localtime being copied into the changeroot
before we set it to the timezone configured by the installer,
resulting in a warning upon rebooting (which would remain
until you either `dpkg-reconfigure tzdata` or `touch /etc/localtime`.

tested minimally with a current PBS iso - the postfix warnings after
rebooting were gone for me.

tested it with a PBS4 installation and PVE9 installation and it
removed the warning in both cases
