add arch32 support for show command

- new behavior will show by default the files available in the arch32
  repo or, if not overwritten by the arch32 repo, the ones available in
  upstream.
- In the special case of PKGBUILD, it will only show the 'patch' file
  in the arch32 repo.
- As always, to check the upstream files, add the -u option.
