run_setup_from_add_tests() has been removed from locitest.

Rich -- I just removed this from the utest/main.c as the most expedient way to unblock the loxigen-artifacts update. 

I see there's a main_template.c from which you originally removed the call to run_setup_from_add_tests() when you removed all the code -- was there some other process that was supposed to update this?
