[libvirt] [PATCH] send 'container=libvirt' in env to container init

[Serge Hallyn]

This allows upstart scripts to detect that they are in a container
and modify their behavior accordingly.

In this way, the same ubuntu maverick or natty image with the 'lxcguest'
package installed can be booted on bare metal, in kvm, or as a
libvirt or liblxc container.
