Disable TARGET_VNDK_USE_CORE_VARIANT if VNDK is deprecated

TARGET_VNDK_USE_CORE_VARIANT enables vendor to use some of the VNDK
libraries with core variant installed in /system/lib. However, this does
not make sense when VNDK is deprecated. This change is to ignore
TARGET_VNDK_USE_CORE_VARIANT when the VNDK is deprecated.
