fix(evm-wallet-experiment): endow crypto on delegation vat in setup scripts

`setup-home.sh` and `setup-away.sh` listed only `TextEncoder`/`TextDecoder`
in the delegation vat's globals, but `delegator-vat.ts` evaluates
`makeSaltGenerator()` at module load, which now unconditionally calls
`crypto.getRandomValues`. Matches the canonical config in `cluster-config.ts`.
