Remove use of private API: SystemVibrator

The use of a new instance of SystemVibrator was introduced in the
following CL:
https://googleplex-android-review.git.corp.google.com/#/q/12c60e42,n,z

to avoid the issue of a competing use of the Vibrator service cancelling
out vibration during an emergency call.

We don't care whether this happens to haptic feedback when tapping on the
dialpad since
1) It is a really short vibration
2) We don't place a new outgoing call while haptic feedback is happening so
it is unlikely to result in competing uses of the Vibrator service
3) Even if haptic feedback for a particular tap is cancelled, it doesn't matter
