Bug 10350 - Capitalization: Home Library column in staff detail items table

"Home library" is incorrectly capitalized on the catalog detail page.
This patch corrects it.

To test, view the normal view of record in the staff client catalog.
The "Home library" table header in the holdings table should be
correctly capitalized.
