Bug#685791: live-build: updated and fixed patch
retitle 685791 support apt.conf.d in lb_chroot_apt
blocked 685791 by 685924
The previous patch adds a feature for add /etc/apt/apt.conf.d/ files
just like the preferences one, but looking at the bug #685924 it is also
affected, so there is an updated patch with the bug fixed too
#685924 needs to be handled first before this can be changed.
