Thanks, Martijn Braam!
* Made postmarketos-mkinitfs use postmarketos-splash to generate splash images
* Added screen sizes to all deviceinfo files
* Bumped pkgrel for all device packages
* Use MIT as license for device-* aports and symlink packages.
That way we don't have the "FIXME" string in the license field,
and the MIT is used by Alpine for internal packages, too.
* linux-* aports: properly name the downloaded files: prefix with
the package name, so it does not just have the git commit as name.
