Configure DomDistiller debug output.

Configure DomDistiller debug output.

Passes the "v" level to DomDistiller for debug output. Now starting
chrome with something like:
out/Debug/chrome --enable-dom-distiller --vmodule=dom_distiller*=1
will log the boilerpipe debug phases to the console.

For content extractor (which doesn't use DomDistillerServiceFactory),
adds a --debug-level flag.

Nit: Totally unrelated, but could you add a comment to this one too? Maybe we
can do it in the future.
