lei: workers exit after they tell lei-daemon

We don't want workers continuing after their stdout has triggered
EPIPE or some other write error.

This fixes xt/lei-onion-convert.t to ensure the quit_waiter_pipe
is fully-closed at daemon teardown during tests.  Using the
`exit' perlop still ensures OnDestroy callbacks will fire.
