Bug 21755: Show patron updated date in circ menu

In borrowers table the column updated_on stores the last updated date and time.
Display this in the circ menu.

Test plan:
1) Go to a patron details page /cgi-bin/koha/members/moremember.pl
2) Look at left menu, you see "Updated on" and a date and time
3) Edit this patron and save
4) Check that "Updated on" changed
5) Click on each tab of menu to check this date is displayed
