Add per-device defaults for VIBRATE_WHEN_RINGING

Some devices have hand-crafted, artisanal haptics to go along with the
dulcet tones of the ringer. When making such a device, we really want
our users to have the opportunity to appreciate the fine buzzes and
clicks we spent so long orchestrating, and so this makes it possible to
default VIBRATE_WHEN_RINGING on.
