Subject: security: Remove pagemap.h includes

The security subsystem does not use the page cache.  Removing just
the pagemap.h includes isn't quite enough to insulate it from changes to
pagemap as it's also pulled in by swap.h and hugetlb.h.  Fortunately,
security doesn't need either of those so we can lose all three.  Now
touching pagemap.h causes no rebuilds in the security subsystem.
