The test case is very similar to reuseport_bpf_cpu, only that here
we select socket members based on current numa node id.

No strong opinion; did this so it aligns with the next lines:
CFLAGS = -Wall -Wl,--no-as-needed -O2 -g
CFLAGS += -I../../../../usr/include/
NET_PROGS = socket
NET_PROGS += psock_fanout psock_tpacket
NET_PROGS += reuseport_bpf reuseport_bpf_cpu reuseport_bpf_numa
