Bug 20676: svc/barcode should allow barcode to be printed without text

Test plan:

1) Point web browser to
   <staff url>/cgi-bin/koha/svc/barcode?barcode=*12345*&notext=1

   This will display a png image of the barcode *12345* with the
   text *12345* printed below the scannable barcode.

2) Apply patch
3) Refresh the browser. The human readable text no longer appears.
