Fix hanging AudioOutputResampler tests.
Fix hanging AudioOutputResampler tests.

The sample rate and buffer size were too small for these tests,
causing FakeAudioOutputStream which runs on the same message loop
to saturate the loop.  Instead use a lower sample rate and larger
buffer size to ensure we don't saturate the loop.

BUG=none
TEST=tsan passes.
