1361: [qemu] fall back to system default machine type r=townsend2010 a=Saviq

1278: Fix delete crash r=Saviq a=ricab

Fixes canonical#1266. `vm_process` is a pointer now and it is null when in off state. Shutdown is called when deleting, which was dereferencing the ptr to kill the process, even if it wasn't there.
