fontconfig cache is not generated reproducibly even with patch from Debian#857892

Originally created by @intrigeri on #12567 (Redmine)

Noticed on #11971 (closed). I’ll attach the actual files and diffoscope output and will check with lamby if he can handle this with the agreed upon budget before June 5.

The package we use is https://deb.tails.boum.org/pool/main/f/fontconfig/fontconfig_2.11.0-6.7.0tails1.dsc

Feature Branch: bugfix/12567-fontconfig-fixup
