fix(chroot): add Dpkg conffile options to prevent interactive prompts

When a cached rootfs contains a modified conffile (e.g. ubuntu-pro-client's
/etc/apt/apt.conf.d/20apt-esm-hook.conf), dpkg prompts during apt-get
install. In a non-interactive chroot stdin is closed, so dpkg reads EOF
and exits with error 1 -- causing the build to fail after 3 retries.

DEBIAN_FRONTEND=noninteractive alone is insufficient: the conffile prompt
is driven by dpkg's own logic and is not suppressed by the frontend var
when stdin is a closed pipe rather than a terminal.

Fix: pass --force-confdef and --force-confold as Dpkg options in the
central chroot_sdcard_apt_get function so all apt-get invocations in
chroot builds resolve conffile conflicts without prompting.

This resolves the Beaglebadge_resolute_vendor_6.18.y_gnome_desktop failure
where ubuntu-pro-client and its 9 dependent packages all failed to
configure because of this conffile prompt.
