Bug 35941: Limit club list to those from the logged in user

Bug 35941: Limit club list to those from the logged in user

clubs-tab get the patron's id from the parameter. At the OPAC we must
use the one from the logged in user, to prevent leak to other users

Test plan:
Have 2 clubs: A, B
Enroll to A with patron borrowernumber=1
Enroll to B with patron borrowernumber=2
Log in with patron 1 and hit:
  http://localhost:8080/cgi-bin/koha/clubs/clubs-tab.pl?borrowernumber=1
=> OK
Now hit
  http://localhost:8080/cgi-bin/koha/clubs/clubs-tab.pl?borrowernumber=2
=> oops

Apply this patch, try again.
The "borrowernumber" parameter is no longer used to fetch the club list.
