DEVELOPERS: trim Carlos Santos' watch list

- I fixed build problems on cups and cups-filters but don't use them.

- gtest, libpam-radius-auth, libpam-tacplus and perl-file-util were
  used in my previous job. I don't have access to the packages that
  use them neither to the corresponding test infrastructure anymore.
