Subject: [PATCH] upgpkg: glibc 2.35-6: package C.UTF-8 locale to be available
 by default

C.UTF-8 is a Unicode aware default locale that is available since glibc 2.35
(https://sourceware.org/glibc/wiki/Proposals/C.UTF-8). It is not directly built
into glibc like the C locale yet, however projects like systemd start relying
on its existence (https://github.com/systemd/systemd/pull/23192).

Therefore let us ship C.UTF-8 with glibc so that it is available by default,
like other major distributions already do. This requires pregenerating the
locale using localedef and installing it to /usr/lib/locale/. Our custom
locale-gen script also needs an updated to avoid removing this locale during
updates (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626575).
