cmd/evm: make staterunner always output stateroot to stderr (#29290) 

This changes makes it so that when `evm statetest` executes, regardless of whether `--json` is specified or not, the stateroot is printed on `stderr` as a `jsonl` line. This enables speedier execution of testcases in goevmlab, in cases where full execution op-by-op is not required.
