[Florian Weimer]

The header file is no longer used on anything but Linux.

2017-11-04  Florian Weimer  <fweimer@redhat.com>

	* bits/mman-linux.h: Move ...
	* sysdeps/unix/sysv/linux/bits/mman-linux.h: ... here.  Update
	comment.
	* sysdeps/unix/sysv/linux/bits/Makefile (sysdep_headers): Remove
	outdated comment.
