futility: update: Skip TPM check if tpm_fwver is not valid.

Ideally we should fail if `tpm_fwver` can't be retrieved, but if an user can
run the updater then his system is already up so it's more likely to be a
vboot library issue (especially in early proto devices) that the crossystem
values were not reported correctly.

As a result, it seems more reasonable to skip checking TPM anti-rollback if
`tpm_fwver` can't be retrieved.
