Add better debugging to `mb run`.

`mb run` (i.e., `python tools/mb.py run`) can be used to run
tests under swarming directly. However, it turns out that there
were a couple of places where we were swallowing error output,
making it hard to understand why things were failing silently :).

This CL should fix at least some of those cases, and also tweaks
the output a bit to be a bit more readable.
