build: configure: Allow to compile tools without libnl
With libnl being made optional in commits 20a5e15443bf ("netsniff-ng: Allow to compile without libnl") and c831bcda3e26 ("trafgen: Allow to compile without libnl"), we can now compile netsniff-ng and trafgen without libnl being present. For now we don't consider libnl and libnl-route separately, meaning that if libnl-route is not present, we disable libnl support entirely. Also add a configure option to explicitely disable building netsniff-ng and trafgen with libnl support. Based on original patch by Vadim Kochan.
