Many of the commands dist test executes are "background" commands run by a work queue system. The work queue allows it to run commands in parallel, but still serialize their output. Currently, the work queue system assumes that exec.Cmd.Stdout and Stderr will be nil and that it can take complete control over them. We're about to inject output filters on many of these commands, so we need a way to interpose on Stdout and Stderr. This CL rearranges responsibilities in the work queue system to make that possible. Now, the thing enqueuing the work item is responsible to constructing the Cmd to write its output to work.out. There's only one place that constructs work objects (there used to be many more), so that's relatively easy, and sets us up to add filters. For #37486.
