remove apt from default suite

Putting the apt recipe in the runlist for the default suite causes kitchen tests to fail for non-debian based systems:

       Recipe: apt::default
         * execute[apt-get-update] action run[2013-11-18T16:03:06+00:00] INFO: Processing execute[apt-get-update] action run (apt::default line 22)
       [2013-11-18T16:03:06+00:00] ERROR: execute[apt-get-update] (apt::default line 22) had an error: No such file or directory - apt-get update; ignore_failure is set, continuing
       
       ================================================================================
       Error executing action `run` on resource 'execute[apt-get-update]'
       ================================================================================
       
       
       Errno::ENOENT
       -------------
       No such file or directory - apt-get update

The recipe was already included in each debian-based platform entry from my previous PR, so this just removes it from the default suite.

Thanks!
