vboot2: Add sd->fw_version_secdata field to communicate to crossystem

Browse Source 
This patchs adds a new vb2_shared_data field to store the current
rollback prevention version number stored in secdata (TPM). This
information needs to be retrieved from there by coreboot (current
hack) or vboot2 kernel verification (bright shiny future) so it can be
passed along to the operating system and user space.

BRANCH=veyron
BUG=chrome-os-partner:35941
TEST=make runtests. Booted Jerry in recovery mode (with corresponding
coreboot patch), ensured that crossystem tpm_fwver still shows the
correct value.
