[PATCH] fix wrong name for HAVE_PTHREAD_SETNAME2 and HAVE_PTHREAD_SETNAME3

[Hajime Tazaki]

even a caller specify a name for rumpuser_thread_create(),
the thread name isn't configured because the
pthread_setname_np(3) is never called.

I guess there are typos in defined name in librumpuser
(rumpuser_pth.c or configure.ac). the following patch is for
rumpuser_pth.c.

it's only debugging purpose, but it is definitely helpful to
investigate the behavior of messy threads.

# yes, I finally started integrating rumpuser to Linux libos.
