Update glibc headers for Linux 4.5.
This patch updates the glibc headers with the defines MADV_FREE,
IPV6_HDRINCL and EPOLLEXCLUSIVE that are added in Linux 4.5.

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

	* bits/mman-linux.h [__USE_MISC] (MADV_FREE): New macro.
	* sysdeps/unix/sysv/linux/hppa/bits/mman.h [__USE_MISC]
	(MADV_FREE): Likewise.
	* sysdeps/unix/sysv/linux/bits/in.h (IPV6_HDRINCL): Likewise.
	* sysdeps/unix/sysv/linux/sys/epoll.h (enum EPOLL_EVENTS): Add
	EPOLLEXCLUSIVE.
