fix: make sure that tutor-openedx is an empty package

Previously, the tutor-openedx package was loading tons of template data from
the MANIFEST.in. Turns out, we cannot ignore the MANIFEST.in file with
setuptools. So we need to move tutor-openedx to a separate, dedicated folder.
To auto-discover the package version, we copy it at runtime (in the make
command).
