thread_sync.c: common wakeup_{one,all} implementation

This let us avoid looping in rb_szqueue_max_set, saves us
some lines of code and reduces binary size slightly
(numbers from 32-bit x86):

         text      data     bss     dec     hex filename
before: 91272       392     156   91820   166ac thread.o
 after: 91200       392     156   91748   16664 thread.o

Inspiration from this taken from the FUTEX_WAKE op
of the Linux futex(2) syscall.
