Vibra: Adapt AOSP (default) vibrator HAL into a hardware module.
Android's implementation of vibrator needs to be done inside a
hardware module, so that it can make a vendor implementation possible.
Hw module's name becomes vibrator.default.so.
This change is related to other changes in:
- frameworks/base
- hardware/libhardware_legacy
- device/generic/goldfish
- platform/build
