Hide Place Hold for, show link to ezproxy uris

For records with uris that match TADL's ezproxy host:

In the search results page:
 - Hide the Place Hold link
 - Show a link to the first uri on the bib

In the record summary page:
 - Hide the Place Hold link

More styling would be good, and potentially putting something where
the "Place Hold" div was in the search results, so that those rows
don't become tiny when the record has no cover art available.
