[PATCH] Fix copyright year

[libcamerabmw+ml at lsmod.de]

From: "Bernhard M. Wiedemann" <bwiedemann at suse.de>

without this patch, openSUSE's debugsource package would vary over time,
breaking reproducible builds.
Also a copyright of 2025 is factually wrong,
because nobody did anything copyright-worthy in that year.
If updating the year manually is too hard (it is optional anyway),
using the mtime of input file(s) could work as well.
