Changed the format on the header, and changed ocache default.
Changed the format on the header, and changed ocache default.

Wanted to make it more readable since there are quite a few variables.
To satisfy existing systems modified the default directory for the
ocache to be located under ${WORKSPACE}/openbmc to maintain function on
some machines that use old defaults. Made a slight change to the cp of
images so now it grabs the whole /deploy directory in case we want sdks.
