configure: use AC_USE_SYSTEM_EXTENSIONS to get _GNU_SOURCE
Let "configure" detect which features are available. Also, nftables is a
Linux project, so portability beyond gcc/clang and glibc/musl is less
relevant. And even if it were, then feature detection by "configure"
would still be preferable.
Use AC_USE_SYSTEM_EXTENSIONS ([1]).
Available since autoconf 2.60, from 2006 ([2]).
