Some of the files need to be adjusted so that they can be used both in cbfstool as well as coreboot proper. For coreboot, add a <sys/types.h> file such that proper types can be included from both the tools and coreboot. The other chanes are to accomodate stricter checking in cbfstool. BUG=chrome-os-partner:48412 BUG=chromium:445938 BRANCH=None TEST=Built on glados including tools. Booted.
