The musl libc exposes some struct tcphdr field only when _GNU_SOURCE is
defined. Fix the following build failure:
nfsynproxy.c: In function ‘parse_packet’:
nfsynproxy.c:34:9: error: ‘const struct tcphdr’ has no member named ‘syn’
if (!th->syn || !th->ack)
^
nfsynproxy.c:34:21: error: ‘const struct tcphdr’ has no member named ‘ack’
if (!th->syn || !th->ack)
^
nfsynproxy.c:42:8: error: ‘const struct tcphdr’ has no member named ‘res2’
if (th->res2 == 0x1)
^
nfsynproxy.c:45:13: error: ‘const struct tcphdr’ has no member named ‘doff’
length = th->doff * 4 - sizeof(*th);
^
