bug(l1): wrong logic when validating peer ForkID

[fmoletta]

When we connect to a peer and exchange Status messages we validate their ForkID, the fork id is derived from the genesis, chain config, and block number and timestamp of the latest block. When we connect to a peer with the purpose of syncing our fork ids will not match, as our peer should be on a further block. Therefore we shouldn't check that our fork ids are the exact same but instead check for compatibility as described in: https://eips.ethereum.org/EIPS/eip-2124
