Expose `NET_CAPABILITY_LOCAL_NETWORK` as public API

Apps that target an SDK before {@link Build.VERSION_CODES.VANILLA_ICE_CREAM}
will not see networks with this capability unless they explicitly set the
NET_CAPABILITY_LOCAL_NETWORK in their NetworkRequests.

In this way, `NET_CAPABILITY_LOCAL_NETWORK` should be public.
