This script allows image signing indipendend of the actual build
process, to run on a master server after receiving freshly backed
images. Idea is to avoid storying private keys on third party builders
while still beeing to be able to sign packages.
Run ./scripts/sign_images.sh with the following env vars:
* TOP_DIR where to search for sysupgrade.bin images
* BUILD_KEY place of key-build{,.pub,.ucert}
* REMOVE_OTHER_SIGNATURES removes signatures added by e.g. buildbots
Only sysupgrade.bin files are touched as factory.bin signatures wouldn't
be evaluated on stock from.
