qmeventd: send QMP 'quit' command instead of SIGTERM

Browse Source 
this is functionally the same, but sending SIGTERM has the ugly side
effect of printing the following to the log:

> QEMU[<pid>]: kvm: terminating on signal 15 from pid <pid> (/usr/sbin/qmeventd)

while sending a QMP quit command does not.
