nptl: Add POSIX-proposed _clock functions to hppa pthread.h
The pthread _clock functions that were recently added to nptl need to be
declared in hppa's pthread.h too. After this change, the function
declaration part of sysdeps/nptl/pthread.h and
sysdeps/unix/sysv/linux/hppa/pthread.h are identical.
* sysdeps/unix/sysv/linux/hppa/pthread.h: Add declarations of
functions recently added to sysdeps/nptl/pthread.h:
pthread_mutex_clocklock, pthread_rwlock_clockrdlock,
pthread_rwlock_clockwrlock and pthread_cond_clockwait.

+ pthread_rwlock_clockwrlock and pthread_cond_clockwait.

* 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.
