Update winrmcp revision to include Windows path fix (#3488)

On Windows, packer's 'file' provisioner fails to copy files/directories that include both a volume identifier (e.g. C:) and spaces in the path.

The root cause of this was found to be embedded single quotes in the 'destination' value, added by the github.com/packer-community/winrmcp/winrmcp project.

This updated winrmcp revision includes the fix to resolve this issue.
