vboot2: vb2_unpack_key2() no longer passes through to vb2_unpack_key()

At one point I thought I'd be able to support both vboot1 and vboot2.1
data structures and dynamically determine which verification path to
run.  But space limitations on current platforms (e.g. pinky) mean
that's not feasible.  Remove this vestigal support, so that it's
easier to make a clean break to the new data structures on appropriate
platforms.

BUG=chromium:423882
BRANCH=none
TEST=make runtests && VBOOT2=1 make runtests (works with/withoug VBOOT2 flag)
     And build firmware for veyron_pinky.
