Build fix for NetBSD.
Build fix for NetBSD.

* src/npth.c (npth_setname_np): conditional check for __NetBSD__ and
adapt correct parameters.
--

Not sure how far back pthread_setname_np() goes on NetBSD. This
function has funny parameters on NetBSD and I *think* this is the
correct
fix (http://www.daemon-systems.org/man/pthread_setname_np.3.html). Fixes
the build anyway.
