template issue: file_groupowner fails tests of itself

#### Description of problem:

The rule `root_permissions_syslibrary_files` uses template `file_groupowner`. During automatus.py rule-based test, the template failed the missing_file_test.pass at initial stage.

These are two causes:
- /lib/dbus-1.0/dbus-daemon-launch-helper has GID 106
- /lib64 is a symbolic link and cause oval to throw: `items were missing:
Object oval:ssg-object_file_groupownerroot_permissions_syslibrary_files_1:obj:1 of type file_object`

Below is the oval result:
