The extra data set by miner configuration should only be set when builder is building payloads to serve.
op-node deriver forces forkchoiceUpdate when pendingSafeL2Head.Number == unsafeL2Head.Number, which causes op-geth to build block with different extra data than it was supposed to, forking the chain.
More investigation is needed when above condition happens. This bug was found when starting the chain from fresh on the devnet, and the op-node seems to force insert some early blocks after genesis block.
This PR is to isolate the extra data modification to the builder module only.
