kbuild: install kernel-page-flags.h

Browse source 
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.

Install the headers and mark the unstable flags as out-of-bounds.  The
page-type tool is also adjusted to not duplicate the definitions
