nptl: Fix Wincompatible-pointer-types on clang

clang 18 issues:

pthread_join_common.c:32:3: error: incompatible pointer types passing 'struct pthread **' to parameter of type 'void **' [-Werror,-Wincompatible-pointer-types]
   32 |   atomic_compare_exchange_weak_acquire (&arg, &self, NULL);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../include/atomic.h:188:39: note: expanded from macro 'atomic_compare_exchange_weak_acquire'
  188 |   __atomic_compare_exchange_n ((mem), (expected), (desired), 1,

Use a void * type instead.
