[PATCH 05/13] demo: Cleanup includes

[Florian Bezdeka <florian.bezdeka@siemens.com>]

- Add an empty line between license information and first include,
  that is what most files already did

- Cleanup unused / unnecessary includes where possible

Signed-off-by: Florian Bezdeka <florian.bezdeka@siemens.com>
