Commit 3c2772650e9 ("imagebuild: tinyipa: Build sha256 checksum files") extended the build process to generate sha256 checksum files for all the tinyIPA files that are uploaded to mirrors. CoreOS builds are also uploaded to mirrors so we need to build similar sha256 checksum files as well. Change-Id: I5de389f14001b6957e4b0aca772edf0e93b35af8
