result directory missing if backend fails before starting fakemachine.service

[obbardc]

If fakemachine errors out before the fakemachine.service is ran, we get an error about not finding the directory:

$ go run cmd/fakemachine/main.go
Running /bin/bash using kvm backend
fakemachine: open /tmp/fakemachine-1054839504/result: no such file or directory

Potentially this links in with #150
