[Devel] New mailing lists.

Hey all,

I've create two new mailinglists (with some initial members):

* Packagers - For those respoensible for the debian package of the      Apertis distribution, including image building. (Used in the    maintainer failed for our various debian packages) * Maintainers - The official maintainers address for the various    apertis components. (Used as the maintainer contact address for the    apertis components).

Apart from these formal usages, these lists will also get the mails from the various jenkins jobs in the near future (e.g. build failures).
