Bug 11932: Move delete checkbox on patron modification to right

To test:
1) Go to Tools -> Batch patron modification
2) Put in a user cardnumber and click Continue
3) Notice checkboxes on the left of the input fields
4) Apply patch and refresh page (resend information if prompted)
5) Notice checkboxes on the right of the input fields
6) Confirm they still work as expected

NOTE: Why not left before the label? And while functional,
      is there a pretty align it nicely with all the other
      checkboxes CSS styling somehow?
