Change Istanbul64 to Istanbul99 (#1903)

When interop testing between Besu and Quorum, it was found
that Quorum's management of the ibft protocol had somewhat
changed, and resulted in besu failing to peer with Quorum

To overcome this, the version of the istanbul protocol in
Besu was upgraded to 99 (matching Quorum's).
