Currently, virCgroupGetPercpuStats is only used by the LXC driver, filling out the CPUTIME stats. qemuDomainGetPercpuStats does this and also filles out VCPUTIME stats. Extend virCgroupGetPercpuStats to also report VCPUTIME stats if nvcpupids is non-zero. In the LXC driver, we don't have cpupids. In the QEMU driver, there is at least one cpupid for a running domain, so the behavior shouldn't change for QEMU either. Also rename getSumVcpuPercpuStats to virCgroupGetPercpuVcpuSum.
