8269851: OperatingSystemMXBean getProcessCpuLoad reports incorrect process cpu usage in containers

[jerboaa]

Hi all,

This issue is present in JDK 17u as well and should get fixed (like the similar JDK-8265836 which made it into JDK 17 GA.) Patch applies clean.

The commit being backported was authored by bobpengxie on 28 Jul 2021 and was reviewed by Severin Gehwolf.

Thanks!
