nptl: Fix niggles with pthread_clockjoin_np

Browse Source 
Joseph Myers spotted[1] that 69ca4b54c1 added
pthread_clockjoin_np to sysdeps/nptl/pthread.h but not to its hppa-specific
equivalent sysdeps/unix/sysv/linux/hppa/pthread.h.

Rafal Luzynski spotted[2] typos in the NEWS entry and manual updates too.

Florian Weimer spotted[3] that the clockid parameter was not using a
reserved identifier in pthread.h.
