Subject: [PATCH] Use run_main_loop_until_done() for process_t tests.

This patch changes the slow process_t tests to use
run_main_loop_until_done() instead of do_main_loop() since
do_main_loop() initializes a lot of subsystem callbacks that we don't
need to run in our tests.

See: https://bugs.torproject.org/28179
