Fix :epipe exits when a command produces output

Erlang acknowledges all captured output that it receives, so acks for
the final bytes are usually still in flight when the child exits.
Exiting then closes the read end of stdin, the ack write fails with
EPIPE, and the port kills the process that called MuonTrap.cmd/3. Wait
for the outstanding acks before exiting instead.

Also handle abnormal port exits in do_cmd/4 so that callers that trap
exits don't wait forever for an :exit_status that will never arrive.

Fixes #98.
