selftests/bpf: fix a compilation error 



I hit the following compilation error with gcc 4.8.5.

  prog_tests/flow_dissector.c: In function ‘test_flow_dissector’:
  prog_tests/flow_dissector.c:155:2: error: ‘for’ loop initial declarations are only allowed in C99 mode
    for (int i = 0; i < ARRAY_SIZE(tests); i++) {
    ^
  prog_tests/flow_dissector.c:155:2: note: use option -std=c99 or -std=gnu99 to compile your code

Let us fix the issue by avoiding this particular c99 feature.
