Bug 25462: Show shelving location on a new line after home library (staff client)

This patch updates the staff client CSS to move the shelving location a
new line after the 'Home library' in list of holdings on the
bibliographic detail page.

To test, apply the patch and rebuild the staff client CSS
(https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_client).

- Locate a title in the staff client which has items with a shelving
  location.
- View the detail page for that title. In the table of holdings,
  confirm that the shelving location information is on a separate line from
  the home library information.
