BuildEventStreamer: support also providing stdout/stderr

Extend the build-event streamer to also report about stdout/stderr,
if provided. This information is reported in the progress events. At
the moment, we only report stdout/stderr in progress events we send
anyway, but the interface is generic enough that we could add time-based
reporting later, if needed. Also note, that at the end of the build, we
report the final progress event, so that all stdout/stderr generated before
the build-complete event get also reported in the build-event protocol.
