shimv2: fix the issue of leaking the hypervisor processes

Browse Source 
Since we only send an shutdown qmp command to qemu when do
stopSandbox, and didn't wait until qemu process's exit, thus
we'd better to make sure it had exited when shimv2 terminated.
Thus here to do the last cleanup of the hypervisor.

Fixes: #2198
