[PATCH common v3 2/2] Fix #7175: replace timezone handling with systemd timedatectl

[Stefan Mayr <stefan@mayr-stefan.de>]

Usage of /etc/timezone is deprecated. The tzdata maintainers recommend
switching to timedatectl.

This removes the deprecated handling of /etc/timezone from the INotify
module.
