distextract was not setting permissions appropriately, for reasons I do
not understand. Fix that, and simplify the code a little. libarchive does
not like overlaid directories with some kinds of set flags, so roll the
distribution files into the 'world' archive for now. This is slightly
bogus, but unavoidable.
