cbfstool: Add 'hashcbfs' command to compute hash of CBFS region.

For the purposes of maintaining integrity of a CBFS allow one to
    hash a CBFS over a given region. The hash consists of all file
    metadata and non-empty file data. The resulting digest is saved
    to the requested destination region.

    TEST=Integrated with glados chrome os build. vboot verification
         works using the same code to generate the hash in the tooling
         as well as at runtime on the board in question.
