Update headers for Linux 4.0, 4.1 definitions

This patch updates installed glibc headers for new definitions from
Linux 4.0 and 4.1 that seem relevant to glibc headers.  In addition, I
noticed that PF_IB / AF_IB, added in Linux 3.11, were missing for no
obvious reason, so added those as well.

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

	* sysdeps/unix/sysv/linux/bits/in.h (IP_CHECKSUM): New macro.
	* sysdeps/unix/sysv/linux/bits/socket.h (PF_IB): Likewise.
	(PF_MPLS): Likewise.
	(AF_IB): Likewise.
	(AF_MPLS): Likewise.
	* sysdeps/unix/sysv/linux/sys/mount.h (MS_LAZYTIME): New enum
	value and macro.
	(MS_RMT_MASK): Include MS_LAZYTIME.

Ping.  This patch 
<https://sourceware.org/ml/libc-alpha/2015-06/msg00746.html> is pending 
review.

netinet/tcp.h in glibc is behind the 4.1 kernel uapi header too.

i assume they are supposed to be consistent.

Feel free to send a patch or file an issue in Bugzilla for whatever 
problems there may be with that header.
