debian: move ubuntu 12.04 files into new backports system

`git diff'ed the main (cmaster) branch against the 12.04 branch
to determine changed debian files, then pulled them into
debian/backports via `git cat-file'. Added 'debian/patches' to
the exclude file, since the existing patches interfere with the
build and are unused by our build. Used '-0~ubuntu12.04+1' as
the version extention, to denote: no patches (-0), debian
packaging files changed for backport (+1).
