vendorcode/eltan/security: Switch to vb2 vboot library

The eltan verified_boot is using the vboot 2.1 data structures and code,
as well as the fwlib21 build target, they are all deprecated. Refer to
CB:37654 for more information.

The verified_boot code is updated to use the vb2 structures and code and
make sure only public functions are used.

BUG=N/A
TEST=build
