Fix ansible paths when provisioning Linux from Windows

Since the paths are generated on the host machine but the commands are
executed on the VM being provisioned the paths generated will use path
separators from the host. In the case of provisioning a Linux VM from
Windows this path will not work.

Convert the path to use a '/' separator which should work for both
platforms in Go
