Small fixes to power-button menu, shell notifications, rotation and packaging
- packaging: Fix package name we look for
- packaging: Don't set build-directory This avoids a local package build messing with the default build dir.
- tests: Enhance landscape config Add x11 and wayland displays as well so it's ease to reuse to verify test failures
- notify-manager: Allow to set a timeout on shell notifications
- top-panel: Remove currently unused actions What comes back will move ot the power-menu.
- top-panel: Close settings before taking screenshot Otherwise it won't be very useful. Screenshots of the settings itself can be made via power-button long press.
