revive-runner: enable PVM logs (#442)

This PR fixes a small oversight from #431: Set the debug config of the
revive-runner `Runtime` such that we get the PVM logs back. Since the
revive runner runtime is mainly meant for debugging, I further decided
to enable unlimited contract sizes and disable [EIP
3607](https://eips.ethereum.org/EIPS/eip-3607) too.
