veyron/tools/playgrount: Add filename and stdout/stderr prefix to output.

This CL prefixes the file output with the file name that it corresponds
to, and also with whether it was sent to stdout or stderr.

In a second step, I will make the stdout/err be JSON-encoded Events,
which the compile server will capture and forward to the client.
