net.server_epoll: Remove delay on last main loop iteration when quitting

Main difference is that timers are not checked unconditionally before
each poll, only when running out of previous poll results (hidden by
util.poll).  This removes a final poll at shutdown that usually delays
the 'not quitting' condition check by one second.
