The mkits.sh prepares a .its file describing a FIT image. This commit
extends it to support a -s option, that allows to pass a file that
should be embedded as a U-Boot script in the FIT image.
This will be used as part of the dm-verity integration to add in the
FIT image a U-Boot script that provides the details of the dm-verity
volume (salt, root hash, number of data blocks, start of hash blocks,
etc.).
