vmware_guest_disk_info/test: ensure the test VM is running

`vmware_guest_disk_info` expects the VM to be running. Since
964783fbd2, `prepare_vmware_tests`
creates the test VM with the `powered-off` state. This to increase
the performance.

This commit ensures the test-suite actually run against a running VM,
as expected.
