[PATCH] mkimage: Allow 'auto-conf' signing of scripts

U-Boot configured for verified boot with the "required" option set to
"conf" also checks scripts put in FIT images for a valid signature, and
refuses to source and run such a script if the signature for the
configuration is bad or missing. Such a script could not be packaged
before, because mkimage failed like this:
% tools/mkimage -T script -C none -d tmp/my.scr -f auto-conf -k tmp -g dev -o sha256,rsa4096 my.uimg
Failed to find any images for configuration 'conf-1/signature'
tools/mkimage Can't add hashes to FIT blob: -1
Error: Bad parameters for FIT image type
This is especially unfortunate if LEGACY_IMAGE_FORMAT is disabled as
recommended.
Listing the script configuration in a "sign-images" subnode instead,
would have added even more complexity to the already complex auto fit
generation code.
