A whole-process monitor has no vcpu list, so omit the 'vcpus' field entirely for cache, memory bandwidth and energy monitors rather than reporting it as an empty string. Return early from the cache collector when there are no monitors, so that a monitor count is not reported when there is no data, matching the memory bandwidth and energy collectors.
