New scripts/fixup and move nulib2-version

Plan to be able to use /usr/local/lib/raspple2 for other things, so
moved the nulib2-version file to a pkginfo subdir.

This gave me an excuse to create something I've wanted for awhile: A
place to stick legacy code that fixes our mistakes that probably doesn't
need to exist forever.  I can count the number of people who downloaded
1f8afb6 on a few fingers of one hand most likely, but the change still
got published and I can silently fix my mistake without having to stick
mostly useless code in install_archive_tools someone's gonna look at
three years from now and ask, "does that still need to be there?"  No,
no it doesn't.  And fixup describes succinctly how long that code needs
to remain there.  And the fix is encapsulated into a nice little blob
that's easily removed when the time comes.
