Serial::xenuse: Send xenuse output to /dev/null

Like sympathy, attaching via xenuse causes xenuse to send output from
the host to its own stdout.

But we don't want the ts-logs-capture stdout to contain this serial
output, interleaved with its own log messages.  We'll capture the
whole serial log from the xenuse logfile.  So redirect it to /dev/null.

I have checked that xenuse does (at least sometimes, eg when given a
nonexistent hostname) use stderr when something actually goes wrong.
