- don't suid before running yum related to rhbz#759443

- if run with root privileges, the debuginfo install script is not
  suided to abrt, but the installed debuginfo files has to be owned by
  abrt:abrt, so they can be removed by abrt (e.d. when trimming old files)
  and that is done using the ensure_abrt_uid decorator
