Download tarballs instead of Git repos for "3rdparty/uvatlas".

This style adjustment makes uvatlas more consistent with the
specification style of all the other third-party dependencies.
Most importantly, it makes it possible to compile Open3D inside
of a chroot jail by simply unpacking the tarballs of all
third-party dependencies into the same workspace.
