cmd/evm: fix gasUsed in evm run cmd (#34732)

In the --create path, execFunc returns gasLeft as the second return
value, but the rest of the code treats this value as "gas used" (printed
as such, and compared in timedExec). This makes gas reporting incorrect
and can cause benchmark consistency checks to fail.
