selftests: bpf: fix compiler warning in flow_dissector test

Add missing header file following compiler warning:

  prog_tests/flow_dissector.c: In function ‘tx_tap’:
  prog_tests/flow_dissector.c:175:9: warning: implicit declaration of function ‘writev’; did you mean ‘write’? [-Wimplicit-function-declaration]
    return writev(fd, iov, ARRAY_SIZE(iov));
           ^~~~~~
           write

Fixes: 0905beec ("selftests/bpf: run flow dissector tests in skb-less mode")
