qemu: Set govmmQemu NoReboot config Knob

Browse Source 
The Kata architecture does not support rebooting VMs (the lifecycle
being start/exec/kill) and if a VM is killed (e.g. using sysrq-trigger),
the VM does not exit fully and other layers do not notice the state change.
Set the NoReboot config Knob so that govmmQemu.LaunchQemu() runs QEMU
with the --no-reboot command-line option.

Fixes: #2866
