Update mirroring procedure

- Removed command output as the names have now changed to
SUSE Liberty Linux instead of Expanded Support, so the
example is no longer needed to avoid confusion

- Changed to --name="Liberty" instead of "Expanded Support"

- RES hasn't changed to SLL though so didn't change that

- Registration procedure might also need name changes, but
I haven't retested it as I don't currently  have room for mirroring
