Subject: [PATCH] seth: update optimism genesis blockhashes

Optimism performed a regenesis which updated the genesis
blockhashes for both mainnet and kovan. For `seth chain` and
any other `seth` commands that rely on `seth chain` to work,
the hardcoded genesis blockhashes need to be updated.

The values were fetched using the following commands:

```
$ seth --rpc-url https://mainnet.optimism.io block 0 hash
0x7ca38a1916c42007829c55e69d3e9a73265554b586a499015373241b8a3fa48b

$ seth --rpc-url https://kovan.optimism.io block 0 hash
0x02adc9b449ff5f2467b8c674ece7ff9b21319d76c4ad62a67a70d552655927e5
```

Tested locally with the commands:

```
$ ./target/debug/seth chain --rpc-url https://mainnet.optimism.io
optimism-mainnet

$ ./target/debug/seth chain --rpc-url https://kovan.optimism.io
optimism-kovan
```
