nptl: Remove unnecessary forwarding of pthread_cond_clockwait from libc

In afe4de7, I added forwarding functions from libc to libpthread for __pthread_cond_clockwait and pthread_cond_clockwait to mirror those for pthread_cond_timedwait. These are unnecessary[1], since these functions aren't (yet) being called from within libc itself. Let's remove them. * nptl/forward.c: Remove unnecessary __pthread_cond_clockwait and pthread_cond_clockwait forwarding functions. There are no internal users, so it is unnecessary to expose these functions in libc.so. * sysdeps/nptl/pthread-functions.h (pthread_functions): Remove unnecessary ptr___pthread_cond_clockwait member. * nptl/nptl-init.c (pthread_functions): Remove assignment of removed member.
