Vibra: Add loading of the vibrator hardware module.

Vibrator HAL is now formed of two hardware modules: one is the default
AOSP and the other is the vendor implementation.

The vendor implementation will be loaded prior to the default one.
For that, the vibrator service has to load the module before
registering itself to the JNI.

This change is related to other changes in:
 - hardware/libhardware
 - hardware/libhardware_legacy
