Fix reporting TPM kernel version and firmware version on ZGB
Fix reporting TPM kernel version and firmware version on ZGB

These fields are part of the version 1 struct, but were mistakenly
labeled as version 2 fields.  Since ZGB firmware produces a version 1
struct, crossystem was treating the fields as unavailable.

BUG=chromium-os:33685
TEST=crossystem tpm_fwver tpm_kernver
BRANCH=none (OS utility change, not firmware, and affects only Alex/ZGB)
