Replace MUTEX_INITIALIZER with _LIBC_LOCK_INITIALIZER in generic code
	* sysdeps/mach/hurd/libc-lock.h (_LIBC_LOCK_INITIALIZER): Define.
	(__libc_lock_define_initialized): Use it.
	* sysdeps/nptl/libc-lockP.h (_LIBC_LOCK_INITIALIZER): Define.
	* malloc/arena.c (list_lock): Use _LIBC_LOCK_INITIALIZER.
	* malloc/malloc.c (main_arena): Likewise.
	* sysdeps/generic/malloc-machine.h (MUTEX_INITIALIZER): Remove.
	* sysdeps/nptl/malloc-machine.h (MUTEX_INITIALIZER): Remove.
