composer: Fix `changed` status that always returns False

re.match in has_changed function never worked properly, because match
requires searched sequence to be present exactly at a start of processed
string, which is not the case here.
fixed zypper.py and zypper_repository.py for SLE10 platform
Enable "ufw default allow routed"

 * The policy is shown in `status verbose`, so all the check mode stuff should keep working.
 * `--dry-run` works as expected.
 * No idea whether it's legal as an argument to `interface`
