Remove Ubuntu keys at end of installation.

The comments have more information, but basically,
because Oz can cache images, and we don't want the
images to all have the same ssh host key, we remove
them at the end of installation, and arrange for
them to be generated at first boot.

Fix a bug with cirrus VGA on Ubuntu 13.04.

It turns out that Ubuntu 13.04 fails to initialize
cirrus VGA, so you get no output on the graphical
console.  This ends up being a kernel bug, so work
around it by disabling the graphical console
automatically at the end of installation.

Add in early check to for Ubuntu customization.

We really can't do customization prior to Ubuntu 11.04,
(since we can't install openssh-server there), so make
that explicit in the code.
