These AudioPlayerBrowserTest run on a target_os="chromeos" linux build
which attempts to use PulseAudio for audio, and always fails [1].

The tests still PASS, since they don't need to test lower-layer audio,
but they do output PulseAudio LOG failure messages. To avoid that, use
a fake audio layer instead, which can be requested by a media command-
line switch kDisableAudioOutput after crrev.com/539638.

[1] PulseAudio won't work in this case and the LOG output of the tests
indicate that (see bug 835626 comments #3 and #7).
