Breakpad: Enable more logging in crash_service to debug flaky failures on Windows

Breakpad: Enable more logging in crash_service to debug flaky failures on Windows

Two things are needed to get crash_service's VLOG(1) messages sent to
stderr:

 * Pass --v=1
 * Enable "SYSTEM_DEBUG_LOG" in InitLogging()

Without these steps, only higher verbosity messages get sent to
stderr.

Note that crash_service's stderr works if stderr is a pipe but not if
it's a Windows console.  On a Buildbot slave, though, stderr is a pipe.

LGTM to the NaCL stuff, but I'd be more confortable if you got sign off on the
crash service stuff from someone who knows the code.

+cpu for tools/crash_service, since you've reviewed my changes there before.

did I father that child? darn. lgtm.

[Mark Seaborn, 2013-01-16 21:56:02]

+thestig since I need an OWNERS review for chrome/tools/crash_service.

[Lei Zhang, 2013-01-16 22:05:09]

lgtm since cpu is happy with it.
