[PATCH v2 1/1] Set default locale in /etc/locale.conf

["Schaffner, Tobias" <tobias.schaffner@siemens.com>]

Debian bookworm introduced systemd-firstboot [1] which asks the user to
configure some basic settings like hostname, timezone or locale if not already
configured.

It asks the user interactively to select a locale on first boot as we do not
have it set in /etc/locale.conf [2].

/etc/locale.conf has the same format as /etc/default/locale.

Symlink /etc/locale.conf to /etc/default/locale for bookworm images to allow
booting without user interaction.
