package/iptraf-ng: really add _GNU_SOURCE in CFLAGS

When iptraf-ng is build with musl, it needs _GNU_SOURCE in CFLAGS to define
the content of "struct tcphdr".

iptraf-ng.mk try to add _GNU_SOURCE in CFLAGS but it's not taken into account.

Add it using IPTRAF_NG_CONF_ENV instead of IPTRAF_NG_MAKE_ENV.
