Bug#1066083: gnome-maps: please make the build reproducible

[James Addison]

Source: gnome-maps
Followup-For: Bug #1066083
X-Debbugs-Cc: lamby at debian.org

Please note: for some other GNOME appdata.xml files, upstream has preferred to
remove dynamic Meson release @date values entirely, which also achieves
reproducibility; that approach might be simpler and perhaps more aligned with
upstream.
