Bug 7550 - Self checkout: limit display of patron image to logged-in patron

The patron image display in the self-checkout takes a GET parameter from the
image source, so if someone copied the image location and substituted the
barcode string they could browse through all patron images:

<img alt="" src="/cgi-bin/koha/sco/sco-patron-image.pl?borrowernumber=XXXX">

To reproduce:
- Enable self checkout, go to [Your Server]//cgi-bin/koha/sco/sco-main.pl
- Log in with a user 'A' who has a patron image
- Copy the address of the patron image into an other browser window
- Change the borrowernumber to on of an other user 'B' having a patron image
- Verify that the patron image is displayed

To test:
- Apply patch, restart plack / memcached
- Try to reproduce
- Verify that you can no longer display the image of user 'B' by
  tweaking the image address
