makefile: add manifest header support
The ISH FW image needs to have a static manifest header prepended to
built ISH image before it can be loaded on to hardware.
The header we prepend is static and is the bare minimum to make the
corresponding shim loader work correctly.
BRANCH=none
BUG=b:122371717,b:124788278
TEST=ec.bin output will chain load properly when sent to the kernel
driver.
