Doug MacEachern 4af1c7f1b2 builder/vmware: Double check that OutputDirectory does not already exist
The initial check in Builder.Prepare does not use the OutputDir interface.
stepPrepareOutputDir also checks if OutputDir exists, error out there unless
using -force so we get the same behavior when RemoteType is esx5.
