Previous commit broke dd(1)'s I/O summary when it's terminated by a

signal.  Fix it by adding an explicit call to summary() in terminate()
(it was previously called implicitly by exit() because summary() was
registered with atexit()).  summary() is supposed to be signal-safe--
it handles SIGINFO almost exclusively--so this should be safe.
