This fix tries to address the issue raised in docker: https://github.com/docker/docker/issues/27540 The issue was that `GetProcessStartTime` use space `" "` to split the `/proc/[pid]/stat` and take the `22`th value. However, the `2`th value is inside `(` and `)`, and could contain space. The following are two examples: ``` ubuntu@ubuntu:~/runc$ cat /proc/90286/stat 90286 (bash) S 90271 90286 90286 34818 90286 4194560 1412 1130576 4 0 2 1 2334 438 20 0 1 0 3093098 20733952 823 18446744073709551615 1 1 0 0 0 0 0 3670020 1266777851 0 0 0 17 1 0 0 0 0 0 0 0 0 0 0 0 0 0 ubuntu@ubuntu:~/runc$ cat /proc/89653/stat 89653 (gunicorn: maste) S 89630 89653 89653 0 -1 4194560 29689 28896 0 3 146 32 76 19 20 0 1 0 2971844 52965376 3920 18446744073709551615 1 1 0 0 0 0 0 16781312 137447943 0 0 0 17 1 0 0 0 0 0 0 0 0 0 0 0 0 0 ``` This fix fixes this issue by removing the prefix before `)`, then finding the `20`th value (instead of `22`th value).
