Bug#1094611: wasistlos: please make the build reproducible

Version: 1.7.0-1

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
wasistlos could not be built reproducibly.

This is because it embeds a date in appdata XML file that varies based
on the build system's timezone.

A patch is attached that requests CMake use the UTC timezone; CMake will
base the underlying value on SOURCE_DATE_EPOCH behind the scenes.
