Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
woof-doom could not be built reproducibly:

│ │ │ │ ├── /usr/share/metainfo/io.github.fabiangreffrath.woof.metainfo.xml
│ │ │ │ │ @@ -35,10 +35,10 @@
│ │ │ │ │    </content_rating>

│ │ │ │ │    </releases>

A patch is attached that uses CMake's "UTC" argument to make sure that
this value does not vary due to the build system's timezone. (CMake is
already magically making the date inherit from SOURCE_DATE_EPOCH.)
