desktop-file-utils generates non-reproducible mimeinfo.cache
In Tails 3.x, we shipped our own patched desktop-file-utils (0.23-1.0tails1) to produce reproducible mimeinfo.cache files. In 4.x, 0.23-4 from Buster is installed instead, which still produce non-reproducible files. The patch lamby upstreamed was only released in 0.24 (available in Bullseye and Sid).
