Update prompt shows the app icon: UPDATE_APP carries the 128 px icon

craft-update's App gains icon_png here: the updater, the self-update helper and
craft-update's startup prompt all get it through crate::UPDATE_APP. The prompt draws it
once craft-libs includes storytold/craft-libs#434; AppImage menu entries get it now.

Clippy fixes for Rust 1.99 in untouched code (same logic):
