[PATCH] meta-isar: Add simple example for injecting prebuilt deb packages

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

While it's definitely nicer and more convenient to pull deb packages
from repos, this may not always be the case. This recipe demonstrates
how to implement such a pattern.

The example embeds the deb as local artifact which is clearly an
anti-pattern. That path was only chosen here because it's hard to find a
stable URL to a prebuilt arch-independent deb file in the wild. The
"sources" and the procedure for creating the deb is also included.

Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

This was only lightly tested because our CI still f...-up thanks to some
primitive content checker at the proxies.
