Bug#704089: tzdata config script prevents non-interactive (re)configuration

[Sébastien Bocahu <zecrazytux@zecrazytux.net>]

Package: tzdata
Version: 2012j-1

The configuration script of the tzdata package, wich uses debconf, prevents
non-interactive (re)configuration of the package.

To reproduce:

- feed debconf with new values for tzdata keys (ex. debconf-set-selections)
- run 'dpkg-reconfigure -fnoninteractive tzdata'
- configuration is unchanged

I propose the following change which makes non-interactive reconfiguration possible:

Note: the comment could make us believe that keys are initialized with the
current values of the debconf database, but it is not the case. These values
are computed from /etc/timezone.

Thanks,
