Extend test_verifier with various test cases around the two kernel
extensions, that is, {rd,wr}only map support as well as direct map
value access. All passing, one skipped due to xskmap not present
on test machine:
# ./test_verifier
[...]
#948/p XDP pkt read, pkt_meta' <= pkt_data, bad access 1 OK
#949/p XDP pkt read, pkt_meta' <= pkt_data, bad access 2 OK
#950/p XDP pkt read, pkt_data <= pkt_meta', good access OK
#951/p XDP pkt read, pkt_data <= pkt_meta', bad access 1 OK
#952/p XDP pkt read, pkt_data <= pkt_meta', bad access 2 OK
