Update libgltf: various fixes, memory usage optimization (second try)

Fixes in the new tarball (beside the upstreamed bug fixes):
- In walkthrough mode camera is moved relative to the current
camera position and not relative to the initial camera position.
- The right FPS numbers are displayed under Linux.
- Some memory optimization to avoid running out of memory
in case of huge models.
- Other freedesktop bugs: fdo#81205, fdo#81207, fdo#81250
