Jake Champlin 2d3ee06ecd Remove LGPL dependencies
This changeset performs the following:

- Updates `masterzen/winrm` vendor to include change from (https://github.com/masterzen/winrm/pull/73).
- Removes `masterzen/xmlpath` dependency, as it is licensed under the LGPL license.
- Updates `dylanmei/winrmtest` vendor to include change from (https://github.com/dylanmei/winrmtest/pull/4).
- Updates `packer-community/winrmcp` vendor to include the removal of the `masterzen/winrm/winrm` sub-class as a result of the `winrm` CLI tool being removed from the `masterzen/winrm` repository.
- Updates nested dependencies as a result of the above vendor changes.
- Refactors `parallels/driver_9` to use `goxpath` instead of `xmlpath`, as `xmlpath` is licensed under LGPL.
- Adds a basic unit test for the refactor work in `parallels/driver_9` to confirm functionality.

This should completely remove any LGPL licensed dependencies inside of the Packer project.
