Add LXC version implementation

Browse Source 
This patch adds an implementation of the version function to the LXC driver.
The providers use the hypervisor version in a field of one of the instances,
so we need to have something meaningful here.  AFAICT, the only real option
we have (considering the limitations of the libvirt version information) is
to use the kernel version.
