[PATCH 5/7] meta-isar/recipes-app: add upstream hello rebuild example

[Henning Schild <henning.schild@siemens.com>]

From: Henning Schild <henning.schild@siemens.com>

This commit introduces a rebuild example of an upstream package. It also
shows how to deal with multiple versions of such a package, depending on
your distro. And in fact we actually have to patch it to rebuild it,
because its build-deps are wrong.
