Subject: [PATCH] Vagrantfile: Don't try to create extant link

`ln` fails if the link already exists. Since 7cbc9233 (Vagrantfile: Bail
out of provisioning if anything fails) this breaks re-provisioning a VM
with `vagrant reload --provision`.

Check if /home/vagrant/lisa already exists and if it does, leave it
alone.
