kbuild: create deterministic initramfs directory listings
kbuild runs "find" on each entry in CONFIG_INITRAMFS_SOURCE that is a directory. The order of the file listing output by "find" matter for build reproducability, hence this patch applies "sort" to get deterministic results. Without this patch, two different machines with identical initramfs directory input may produce differing initramfs cpio archives (different hash) due to the different order of the files within the archive.
