Fix EIP-2124 Fork identifier for chain compatibility checks. (#1050)

Browse Source 
Before this pull request Besu was using the latest known fork id to create status message for Ethereum P2P protocol handshake.
This latest known fork id was created based on a list of forks retrieved from the Genesis.
For private networks it is possible that all fork blocks number are set to 0.
The algorithm to compute the valid fork hashes excludes 0 values.
As a result, the list was empty and the `getLatestForkId` was returning `null`. This is an issue when you support capabilities >= to Eth/64 sub protocol because other peers expect the fork id value in the `RLP` encoded message.
Moreover, the algorithm to compute the fork id should be aware of the chain head number and update `CRC` value only for fork blocks below the current head.
This pull request fixes this issue by fetching the chain head number and update accordingly the `CRC` value.
Unit tests have been extended to cover an exhaustive list of possible combinations on named networks (`goerli`, `rinkeby`, `ropsten` and `mainnet`).
