kvm_monitor.py: is_responsive(): Use status command

The is_responsive() method in QMPMonitor class uses the query-version command to check if the monitor is alive and the same method in the HumanMonitor class uses the help command.

This commit changes both classes to use the status command instead, so that:

o The QEMU's response is shorter when using the Human Monitor. The help command output is 70 lines long, which makes it a bit expansive for a single ping

o is_responsive() can be extended to check if QEMU is running

o My logs won't be flooded with help's output :-)
