unl0kr.conf: Add a commented timeout= parameter
Just for documentation - distros are expected to enable it manually if desired.
(was: Set default timeout to 5 minutes, for real, old MR description follows)
Follow up to !5 (merged)
@cherrypicker you were actually correct, the commit was there but I forgot to add the changed configuration file!
Sorry for the noise!
