Youlin Li 475244f5e0 selftests/bpf: Add verifier test for release_reference() 
Add a test case to ensure that released pointer registers will not be
leaked into the map.

Before fix:

  ./test_verifier 984
    984/u reference tracking: try to leak released ptr reg FAIL
    Unexpected success to load!
    verification time 67 usec
    stack depth 4
    processed 23 insns (limit 1000000) max_states_per_insn 0 total_states 2
    peak_states 2 mark_read 1
    984/p reference tracking: try to leak released ptr reg OK
    Summary: 1 PASSED, 0 SKIPPED, 1 FAILED

After fix:

  ./test_verifier 984
    984/u reference tracking: try to leak released ptr reg OK
