Fix race condition when configuring the qemu save directory

Browse Source 
The /var/lib/libvirt/qemu/save directory is not actually created
by the installation of libvirt-bin, it is created by libvirt upon
startup. So if libvirt is slow to initialize and this task runs
before the directory is created, then the next task:
"Check if the qemu save directory is empty" will fail with:
stderr: ls: cannot access /var/lib/libvirt/qemu/save: No such file or directory
