MINOR: haproxy: process signals before runnable tasks

Browse Source 
Nowadays signals cause tasks to be woken up. The historic code still
processes signals after tasks, which forces a second round in the loop
before they can effectively be processed. Let's move the signal queue
handling between wake_expired_tasks() and process_runnable_tasks() where
it makes much more sense.
