cbdb1461dc selftests/bpf: Use explicit bpf_prog_test_load() calls everywhere 
-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and
breaks when deprecation goes into effect due to macro magic. Convert all
the uses to explicit bpf_prog_test_load() calls which avoid deprecation
errors and makes everything less magical.

fe993c6468 selftests/bpf: properly return error from bpf_flow_load 
Right now we incorrectly return 'ret' which is always zero at that
point.

0905beec9f selftests/bpf: run flow dissector tests in skb-less mode 
Export last_dissection map from flow dissector and use a known place in
tun driver to trigger BPF flow dissection.

bf0f0fd939 selftests/bpf: add simple BPF_PROG_TEST_RUN examples for flow dissector 
Use existing pkt_v4 and pkt_v6 to make sure flow_keys are what we want.

Also, add new bpf_flow_load routine (and flow_dissector_load.h header)
that loads bpf_flow.o program and does all required setup.
