jmx-dev RFR: 8283903: GetContainerCpuLoad does not return the correct result in share mode

[xpbob]

```        
               long hostTicks = getHostTotalCpuTicks0();
                int totalCPUs = getHostOnlineCpuCount0();
                int containerCPUs = getAvailableProcessors();
                // scale the total host load to the actual container cpus
                hostTicks = hostTicks * containerCPUs / totalCPUs;

hostTicks=175476155560000000
totalCPUs=96
containerCPUs=90

Calculate the overflow
