Bug 10619 - fix errors in sco.css for the CCSR OPAC templates

sco.css is not missing from CCSR, but some image paths in the CSS are
incorrect, resulting in some missing images. This patch corrects those
broken paths.

This patch also hides the Cart/Lists/login region of the template which
should not be visible in self checkout.

To test, enable self-checkout and switch to the CCSR theme. Load a
patron for self-checkout and confirm that images associated with buttons
appear correctly: By the help link in the upper-right, on the 'Finish'
button, etc. Try checking out an item which is already checked out to
that patron to see more examples.
