* Use name.sh functions for paths in genimage Paths for images generated outside of genimage were not used in genimage definitions. Use them as the single source of truth. Images generated by genimage itself (e.g. kernel.img) don't need to use those functions, so remove the unused ones. * Use EROFS instead of SquashFS for root FS * Enabled EROFS in common kernel fragment * RootFS image switched to EROFS with options to get decent compression * rootfstype removed from kernel command line * Get size of correct FS image in GH build summary
