[L/unstable 04/13] UBUNTU: [Packaging] use dpkg-parsechangelog to get package name and series

[Masahiro Yamada]

dpkg-parsechangelog is more readable than the complex regex matching.

Also, use the simple variables (:=) instead of recursive variables (=)
since these are used over and over again. Invoking the shell every time
is not efficient.
