Errors about elevating to root

[SkewedZeppelin]

On a build from 52c8179 when any jailed application is exited while running via signal 2 (ctrl+c) a few seconds after fully exiting and dropping back to the shell the following messages are printed. And monitoring the running processes, after the original process exits the firejail process lingers until after the messages are printed. The sandbox seems to be created and functioning just fine, and --debug shows no errors.

31e407b seems to be the commit that introduced this issue.
