remote: increase daemon shutdown timer to 2 minutes

Shutting down the daemon after 30 seconds of being idle is a little bit
too aggressive. Especially when using 'virsh' in single-shot mode, as
opposed to interactive shell mode, it would not be unusual to have
more than 30 seconds between commands. This will lead to the daemon
shutting down and starting up between a series of commands.

Increasing the shutdown timer to 2 minutes will make it less likely that
the daemon will shutdown while the user is in the middle of a series of
commands.
