vboot: Do not use hashed-strings offset
The hashed-strings signature property includes two uint32_t values. The first is unneeded as there should never be a start offset into the strings region. The second, the size, is needed because the added signature node appends to this region. See tools/image-host.c, where a static 0 value is used for the offset.
