While working on CL 528798, I found out that sys.PidFD field (added in CL 520266) is not filled in when CLONE_NEWUSER is used. This happens because the code assumed that the parent and the child run in the same memory space. This assumption is right only when CLONE_VM is used for clone syscall, and the code only sets CLONE_VM when CLONE_NEWUSER is not used. Fix this, and add a test case (which fails before the fix). Updates #51246.
