selftests/bpf: Test access to ringbuf position with map pointer
Add the testing to access the bpf_ringbuf with the map pointer.
"consumer_pos" and "producer_pos" is accessed in this testing. We reserve
128 bytes in the ringbuf to test the producer_pos, which should be
"128 + BPF_RINGBUF_HDR_SZ".
It will be helpful if we want to evaluate the usage of the ringbuf in bpf
prog with the consumer and producer position.
