Exclude symlinks for accounts_users_home_files_permissions

[scmeli]

Description of problem:

The accounts_users_home_files_permissions rule does not exclude symbolic links. A symlink in a users' home directory fails the check since its permissions are always lrwxrwxrwx which is greater than 750.

Proposed change:

Add a filter to the object_accounts_users_home_files_permissions_files object to exclude symbolic links.

<oval-def:filter action="exclude">oval:ssg-state_accounts_users_home_files_permissions_files_symlink:ste:1</oval-def:filter>

<unix:file_state id="oval:ssg-state_accounts_users_home_files_permissions_files_symlink:ste:1" version="1">
  <unix:type operation="equals">symbolic link</unix:type>
</unix:file_state>
