include: don't define _GNU_SOURCE in public header

_GNU_SOURCE is supposed to be defined as first thing, before including any
libc headers. Defining it in the public header of nftables is wrong, because
it would only (somewhat) work if the user includes the nftables header as first
thing too. But that is not what users commonly would do, in particular with
autotools projects, where users would include <config.h> first.

It's also unnecessary. Nothing in "nftables/libnftables.h" itself
requires _GNU_SOURCE. Drop it.
