Update set_path for MRtrix3Tissue user experience

This should help users migrating from an existing MRtrix3 installation, or hopefully avoid confusion in general. While it should always be clear to them that MRtrix3Tissue is an MRtrix3 fork (e.g. in GitHub repository description, as well as overt GitHub forking network), they might appreciate some hints that they've successfully installed and are then running MRtrix3Tissue. The PATH is one such place to avoid confusion at all costs.
