Backup doesnt work when rootfs have a different location from /var/lib/lxc

[apinela]

I use different locations for my containers rootfs, since the code for backup them have hardcoded the rootfs path, this needs some fix:

Hi @apinela,
I will be happy to merge your improvements as well as add you (or anyone else that is actively using this project) as developer here!

stock ubuntu 16.04 uses /var/lib/lxd

/var/lib/lxc is empty

ie the panel drops containers at /var/lib/lxc/CONTAINER_NAME
mine from command line are placed at /var/lib/lxd/containers/CONTAINER_NAME
