Update sysdeps/unix/sysv/linux/bits/socket.h for Linux 4.6


This patch updates sysdeps/unix/sysv/linux/bits/socket.h for new
constants added in Linux 4.6.  AF_KCM / PF_KCM are added.  SOL_KCM is
new, and I added a lot of SOL_* values postdating the last one present
in the header, since I saw no apparent reason for the set in glibc to
stop at SOL_IRDA.  MSG_BATCH is added; Linux also has
MSG_SENDPAGE_NOTLAST which is not in glibc, but given the comment
starts "sendpage() internal" I presume it's correct for it not to be
in glibc.

(Note that this is a case where the Linux kernel header with userspace
relevant values is *not* a uapi header but include/linux/socket.h - I
don't know why, but at least this header, as well as uapi headers,
needs reviewing for glibc-relevant changes each release.)

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
