jdk_container left files owned by root

`jdk_container` left files on the host machine that are owned by root. These files cannot be cleaned by Jenkins job. It causes Jenkins job to fail.

@sophia-guo @smlambert do you also see a similar issue at Adoptium Jenkins? Is there a better way to resolve this?

Start by locating the jdk_container implementation and the Jenkins execution path that creates the reported workspace files. Reproduce the cleanup failure and verify that files left on the host are removable by the Jenkins job without root ownership.
