vndkMustUseVendorVariantList += vintf-vibrator

TARGET_VNDK_USE_CORE_VARIANT devices explicitly track libs which are
differentiated between system/vendor. b/145157349 is filed to try to
catch these errors during normal builds (or in presubmit).

aidl libs need to be differentiated because they explicitly set
different system/vendor stabilities.
