This is meant to mirror sudo's -k/--reset-timestamp and -K/--remove-timestamp options, which revoke the temporary authorization provided by the timestamp files in /var/run/sudo/ts. To achieve the same effect in run0, we ask polkit to revoke our temporary authorization. If used with a command, run0 will revoke the temporary auth and then immediately authorize the user again, just like sudo -k. All the bus calls are completed synchronously, as they need to complete before authorizing the user anyway. Like sudo, the effect of -k/--reset-timestamp is to revoke only the tmpauthz that polkit would have used to authorize the command, if available. The -K/--remove-timestamp option will revoke all temporary authorizations across all ttys.
