[libvirt] [OSSTEST PATCH 2/2] libvirt: Do not attempt save/restore when migration not advertised

Currently, osstest wrongly thinks that ARM can do save/restore, because `virsh help' does mention the save command (on all architectures). Additionally, check the virth capabilities xpath /capabilities/host/migration_features to try to see whether this host supports migration. I am not sure if this is the right path to check. Perhaps /capabilities/host/migration_features/live is more correct, but this may be wrong if Xen comes to support save/restore on ARM, but not live migration (but perhaps libvirt cannot express this distinction in which case perhaps it's right after all).
