Bug 7657 - Google and OpenLibrary image conflict

The JavaScript files which output Google and OpenLibrary cover images
each assumes it is the only source for cover images running. Each script
isn't specific enough to filter out markup generated by the other. This
patch corrects the specificity of the selector looking for markup
related to Google and OpenLibrary covers.

To test, enable both Google and OpenLibrary cover images in the OPAC.
Perform a search which will return results which include titles which
have covers from both services. Confirm that these covers appear
correctly and that "no cover" information still works correctly.
