This patch adapts the patron image display script from the
self-checkout module to optionally display the image of the
logged-in user on their personal information page (opac-userupdate.pl).
The script changes the method choosing which image to display
from using a passed cardnumber to using the borrowernumber of
the logged-in user.
A system preference is added, OPACpatronimages, to control
whether these images are displayed.

Verified that patron image shows only when system preference is turned on
and that there are no display problems for patrons without patron image.
