Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
displaycal-py3 could not be built reproducibly.

This is because the /usr/share/metainfo/net.displaycal.DisplayCAL.appdata.xml
file contained the current date:

│ │ │ │ │      <id>dispcalGUI.desktop</id>
│ │ │ │ │      <id>displaycal.desktop</id>
│ │ │ │ │    </provides>
│ │ │ │ │    <releases>
│ │ │ │ │ -    <release version="3.9.19" date="2026-08-05">
│ │ │ │ │ +    <release version="3.9.19" date="2027-09-08">

Patch attached that seeds this from SOURCE_DATE_EPOCH, if it exists.
