emmc-image: add verification script for security service
This provides a script to verify all the emmc images
Time comsuming should be trivial, 800k image takes 0.04s to verify.
Tested:
time veritysetup --data-block-size=$DATA_BLOCK_SIZE --hash=$HASH_ALGORITHM --hash-block-size=$HASH_BLOCK_SIZE --hash-offset=$DATA_SIZE verify "${emmcdir}/${img}" ${emmcdir}/${img} $ROOT_HASH
real 0m0.043s

root@thl6-nfd01:~# time /usr/bin/emmc-image-verify.sh
