[RHEL/6] Exclude /home directory itself from scan when checking if user's home
directories are not group-writable or world-readable. Move the check to shared.
[RHEL/7] Add symlink to the shared/ script.
[Fedora] Add session guide chapter & create symlink to shared file_permissions_home_dirs
OVAL check.
[shared] Fix typo in couple of test_attestation's (should be ref_id, not red_id)
[RHEL/6, RHEL/7, Fedora] input/system/accounts/session.xml:
* fix couple of instances of EOL whitespace noise,
