vboot: Add vb2_unpack_key_buffer

Browse Source 
Previously, vb2_unpack_key() actually unpacked a key buffer.  Callers
that had a vb2_packed_key had to typecast it back to a uint8_t buffer to
unpack it.  Rename vb2_unpack_key() to vb2_unpack_key_buffer(), and make
vb2_unpack_key() unpack a vb2_packed_key.

BRANCH=none
TEST=make runtests; emerge-kevin coreboot depthcharge;
     emerge-samus and boot it
