chromeec: Move EC image hash to separate file in CBFS

The Chrome OS bootloader is changing its EC software sync mechanism to
    look for the hash of an EC image in a separate CBFS file, rather than
    using the CBFS hash attribute of the image itself (see
    http://crosreview.com/348061). This patch makes coreboot generate
    appropriate hash files for the new format when it builds and bundles a
    Chrome EC image. This also allows us to compress the EC image itself.
