Add Media.UnderflowDuration2.* histograms.
This histogram replaces the Media.UnderflowDuration.* histograms, which
is deprecated in this change.
The primary difference is that Media.UnderflowDuration2.* will only
account for rebuffers. Today, the Media.UnderflowDuration.* histograms
accounts for initial zero samples, which were previously reported to
compensate for playbacks that never rebuffer.
