rambox: migrate to use AppImage

The motivation comes from PR #108787: AppImage is the official and
using it should avoid some issues.

Also, migrating both packages (instead of only rambox-pro like #108787)
can make maintaining both packages better. There is now a `mkRambox`
function that abstract most of the build process.
