cbfstool: Add support for hashes as file metadata

Hardware / Coreboot - Patrick Georgi [georgi-clan.de] - 1 October 2015 15:14 UTC

They allow optimizing a verification of a whole CBFS image by only dealing with the headers (assuming you choose to trust the hash algorithm(s)).

The format allows for multiple hashes for a single file, and cbfstool can handle them, but right now it can't generate such headers.

Loosely based on Sol's work in http://review.coreboot.org/#/c/10147/, but using the compatible file attribute format. vboot is now a hard dependency of the build process, but we import it into the tree for quite a while now.
