Instead of having a separate liftoff config, which is tested against the default (which currently means tier-up from liftoff to turbofan), just choose reasonable liftoff configs for the existing configs. 'ignition' now implies pure liftoff execution. 'ignition_turbo_opt' always compiles with turbofan. Other configs use the default (tier up).
