runsc/debug: add an option to list all processes

runsc debug --ps list all processes with all threads. This option is added to
the debug command but not to the ps command, because it is going to be used for
debug purposes and we want to add any useful information without thinking about
backward compatibility.

This will help to investigate syzkaller issues.
