fix: Only call get_all_running_processes_info when needed

[mihaitodor]

Do not call get_all_running_processes_info() unless the log level requires printing debug logs.

When running micromamba in a specific production environment, we keep getting Segmentation fault (core dumped) and, by adding more logs in the code, I was able to narrow it down to this particular log entry, where it tries to print the currently running processes. I can confirm that the crash doesn't occur in get_all_running_processes_info() and it is something in the MessageLogger implementation, but I have a hard time narrowing it down since I don't have access to run gdb in that environment or collect core dumps. I believe it is something to do with the length of the resulting string, but I've not been able to get it to reproduce reliably in a unit test. However, we don't use debug logs and, in this case, I think the code should skip this log clause completely, which should unblock us.

Thank you, @mihaitodor.

Indeed get_all_running_processes_info only must be called when needed.
