selftests/bpf: Fix compiling kfree_skb.c with musl-libc
[ Upstream commit bae9a5ce7d3a9b3a9e07b31ab9e9c58450e3e9fd ]
The GNU version of 'struct tcphdr' with member 'doff' is not exposed by
musl headers unless _GNU_SOURCE is defined. Add this definition to fix
errors seen compiling for mips64el/musl-libc:
In file included from kfree_skb.c:2:
kfree_skb.c: In function 'on_sample':
kfree_skb.c:45:30: error: 'struct tcphdr' has no member named 'doff'
45 | if (CHECK(pkt_v6->tcp.doff != 5, "check_tcp",
| ^
