tests: change policy for new tcb claims extension

We query the TCB claims to see which platform the evidence came from.
Now that the TCB claims are in a new place, the policy will need to be
adjusted slightly.

This is a bit inconvenient but it shows why it's important to use the
right extension in the first place. It's potentially very confusing to
see veraison stuff in our policy.
