vboot: remove vboot_handoff.h from chromeos.h

chromeos.h includes vboot_handoff.h, which includes vboot_api.h. since
vboot_api.h is not available to non-chromeos projects, build fails for
some boards (e.g. glados).

this change removes (unnecessary) inclusion of vboot_handoff.h in chromeos.h
and fixes other files which rely on indirect inclusion of vboot_handoff.h
by making it direct.

BUG=none
BRANCH=tot
TEST=built for cosmos, falco, lumpy, nyan_blaze, parrot, rambi, rush_ryu,
samus, storm, veyron_pinky
