Vibra: emulator: compile and stage vibrator.goldfish

Following the new vibrator hardware module implementation, the
goldfish vibrator module is no longer integrated in the default
vibrator implementation and therefore needs to be explicitly built
for the emulator.

This patch is related to others in:
 - hardware/libhardware
 - hardware/libhardware_legacy
 - frameworks/base
 - device/generic/goldfish
