The GNU version of 'struct tcphdr' has members 'doff', 'source' and 'dest',
which are not exposed by musl libc headers unless _GNU_SOURCE is defined.

Add this definition to fix errors seen compiling for mips64el/musl-libc:

  flow_dissector.c:118:30: error: 'struct tcphdr' has no member named 'doff'
    118 |                         .tcp.doff = 5,
        |                              ^~~~
  flow_dissector.c:119:30: error: 'struct tcphdr' has no member named 'source'
    119 |                         .tcp.source = 80,
        |                              ^~~~~~
  flow_dissector.c:120:30: error: 'struct tcphdr' has no member named 'dest'
    120 |                         .tcp.dest = 8080,
        |                              ^~~~
