The just-landed 6f64eeab605 (Merge branch 'es/trace2-log-parent-process-name', 2021-08-24) added parent process name logging, but under Linux we'd only log the immediate parent, and the full process chain on Windows. This brings the Linux implementation in parity with the Windows implementation. As it turns out /proc/<PID>/stat is a bit of a pain to parse. This is preceded by some minor memory leak fixes to es/trace2-log-parent-process-name, and the fixing of a bug where we'd log the empty string as a parent if we didn't have procfs.
