[PATCH 1/8] guestfs: Fix Debian 13 (Trixie) APT sources file path

Debian 13 (Trixie) changed from using a single /etc/apt/sources.list
file to the new DEB822 format in /etc/apt/sources.list.d/debian.sources.

This was causing virt-customize to fail during base image creation with:
  virt-customize: error: libguestfs error: source '/etc/apt/sources.list'
  does not exist (or cannot be read)

Add a conditional default for GUESTFS_DISTRO_SOURCE_AND_DEST_FILE that
uses the new path for Debian Trixie while preserving the old path for
other Debian versions.
