[PATCH] Install kernel-page-flags.h

[Ulrich Drepper <drepper@akkadia.org>]

Programs using /proc/kpageflags need to know about the various flags.  The
<linux/kernel-page-flags.h> provides them and the comments in the file
indicate that it is supposed to be used by user-level code.  But the file
is not installed.

The patch below installs the headers and marks the unstable flags as
out-of-bounds.
