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

Before this change, the following would fail for me:

  make headers_install
  make M=Documentation/networking/timestamping


  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.

Fixes: cd91cc5b
