build with the --ppa, apt-line duplicated

[Hajime Mizuno]

I run ubuntu-defaults-image with a --ppa option.
ISO Images that have been built, include "ubuntu-defaults.chroot.list" and "ubuntu-defaults.binary.list".
These contents are identical. As a result, I failed to apt-get update (duplicate apt-line).

ubuntu-defaults.chroot.list, in the image that has been built should be removed.

build command:
$ ubuntu-defaults-image --ppa mizuno-as/ppa

Live session in builded image:
$ ls /etc/apt/sources.list.d/
ubuntu-defaults.binary.list ubuntu-defaults.chroot.list

$ sudo apt-get update
(...snip...)
W: Duplicate sources.list entry http://ppa.launchpad.net/mizuno-as/ppa/ubuntu/ quantal/main i386 Packages (/var/lib/apt/lists/ppa.launchpad.net_mizuno-as_ppa_ubuntu_dists_quantal_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

I seems that chroot.list and binary.list were deprecated, and we should use list.chroot and list.binary instead.

But we don't need to have a separate content for chroot/binary to add PPA, so I unified those in the attached branch.

This bug was fixed in the package ubuntu-defaults-builder - 0.47
