nptl: Move pthread_once and __pthread_once into libc
And also the fork generation counter, __fork_generation. This eliminates the need for __fork_generation_pointer. call_once remains in libpthread and calls the exported __pthread_once symbol. pthread_once and __pthread_once have been moved using scripts/move-symbol-to-libc.py.
