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.
