Build xskxceiver, xdp_hw_metadata, and xdp_features from explicit source lists instead of reusing helper objects produced by test_progs rules. Reusing shared objects such as network_helpers.o and xsk.o can pull in test_progs-only dependency chains and trigger unrelated libarena builds when invoking a single target. Keep these standalone binaries self-contained so each target builds only its own required sources and BPF skeleton dependencies.
