Bug 14566: Fix permissions in patronimage.pl

There is no permission needed to access the patronimage.pl script.
This means anybody cans access to the patron's images.

Test plan:
Add an image to borrowernumber 42 and call
/cgi-bin/koha/members/patronimage.pl?borrowernumber=42

If you are logged in with borrowers permissions, you will see the image,
otherwise you will get a blank page with a 403 header.
