It appears "cleanup: False" no longer works

[aaronbell]

If I do not want ninja to clean up the build files, for whatever reason, it would be helpful to set cleanup: False in the builder config. However, it does not appear to do anything anymore as it is not mentioned anywhere else in the builder code. I think it would be helpful to be able to disable cleanup.
