bin/neubotw: Comment LOG.redirect() out and unbreak Win7

Before-release testing caught this case where neubotw.exe fails
because it's not privileged and therefore cannot register its own
event source.  Put it another way, under Win7 you cannot log unless
you manage to create an event source with a privileged process.

The release is due as soon as possible, and I don't want to roll
out a patchy solution (particularly because the Windows environment
is, at least for me, quite unpredictable).  So this patch just
comments LOG.redirect() out.

Thanks to Roberto D'Auria that helped with troubleshooting.
