chrome --headless shouldn't crash if there is no soundcard.

Project Member Reported by alexclarke@chromium.org, Jan 6 2017 
Chrome Version: 57.0.2970.0
OS: Linux

We are getting reports of a crash when running chrome within a docker container that doesn't have sound support

Running with " --headless --no-sandbox --disable-gpu --dump-dom http://atelyeah.de"

Getting following output:

Turns out this has nothing to do with audio. The actual crash is caused by the power save blocker not being able to talk to X11.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/28b1bf2e4e780f510109ca4b1d61e72f024232aa

commit 28b1bf2e4e780f510109ca4b1d61e72f024232aa

power save blocker: Don't try to block power saving in headless mode

When running headless mode, there's no need to block power saving as
there is no available display server. This patch makes PowerSaveBlocker
early-out in such a case (on X11).
