Move vendor module into base_vendor

There is a vendor module android.hidl.memory@1.0-impl.vendor which is
defined in the base_system. Based on the definition of base_system.mk
and base_vendor.mk, this module is better to be located in the
base_vendor.mk. This change moves the module from base_system into
base_vendor.
