update flashtestation logic to use new workload ID computation#331

Conversation
To account for a bug in the xfam and tdAttributes bitmasking logic, we changed the way the workload ID is calculated in the BlockBuilderPolicy. That PR is here: flashbots/flashtestations#53 This means the workload ID calculation needs to change in any upstream services, which includes op-rbuilder. I've made the same change that I made in the solidity contract here in the attestation.rs logic where op-rbuilder calculates the workload ID. The tests have been updated to use the new correct workload ID, which I obtained by running the BlockBuilderPolicy:workloadIdForTDRegistration function on the same TEE registration that is used in the tests.
