doc: fix the compile fix of txtimestamp.c
A fix to ipv6 structure definitions removed the now superfluous definition of in6_pktinfo in this file. But, use of the glibc definition requires defining _GNU_SOURCE (see also https://sourceware.org/bugzilla/show_bug.cgi?id=6775). Before this change, the following would fail for me: make make headers_install make M=Documentation/networking/timestamping with Documentation/networking/timestamping/txtimestamp.c: In function '__recv_errmsg_cmsg': Documentation/networking/timestamping/txtimestamp.c:205:33: error: dereferencing pointer to incomplete type Documentation/networking/timestamping/txtimestamp.c:206:23: error: dereferencing pointer to incomplete type After this patch compilation succeeded.
