hurd: Fix bits/socket.h conformity
* sysdeps/mach/hurd/bits/socket.h: Include <bits/wordsize.h> instead of <limits.h> (__need_NULL): Do not define. (__ss_aligntype): Use __WORDSIZE instead of ULONG_MAX to determine alignment. [!__USE_MISC] (pseudo_AF_XTP, pseudo_AF_RTIP, pseudo_AF_PIP, CMGROUP_MAX, cmsgcred): Do not define. (CMSG_FIRSTHDR, __cmsg_nxthdr): Use (struct cmsghdr *) 0 instead of NULL. * bits/socket.h: Likewise.
