Bug 24953: Minor corrections to hold ratios report sidebar

This patch makes some minor corrections to the sidebar form on the hold
ratios report page:

 - Correct markup errors
 - Change the text of labels from "included" to "include"
 - Move checkboxes to the left of labels

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)

 - Go to Circulation -> Hold ratios
 - In the sidebar, confirm that the labels "Include ordered" and
   "Include suspended" appear to the right of their associated
   checkboxes.
 - Validate the source of the page. There should be no errors.
