set hostname for 1.0 as required by provisioning

In a fresh checkout:

    $ ( cd development; ln -s Vagrantfile{.1.0,}; vagrant up )

Was failing with:

    err: /Stage[main]//Exec[config-lxc]/returns: change from notrun to 0
    failed: cp /vagrant/development/lxc-configs/quantal64 /etc/default/lxc
    returned 1 instead of one of [0] at
    /tmp/vagrant-puppet/manifests/site.pp:19

because the hostname was "quantal64" and the puppet manifest attempts to
install the lxc-config based on the hostname name of the VM.
