Update nevermind bad-iszero patch for EvmWord rename

Upstream Nethermind renamed the per-file `using Word = Vector256<byte>;`
alias to a project-wide `<Using ... Alias="EvmWord" />` in
`src/Nethermind/Directory.Build.props` (PR #11436), so all `Word` usages
in `EvmInstructions.Math1Param.cs` are now `EvmWord`. The patch's context
no longer matched, breaking the `master-bad-iszero` image build.
