Update libgltf: new build system and various fixes

Building:
- The new tarball has reasonable build system so
build libgltf as external package instead of compiling
source files directly.
- Freetype dependancy is removed

Improvements comes with the new libgltf
- Can rotate the models too (orbit mode)
- Two camera handling mode: walkthrough and orbit
(press M to change).
- gltf_animation_set_time() works
- FPS can be displayed without freetype (press F)

Additional notes:
- There were some bugs/regressions which are fixed
during the integration (see patches).
- License files are uddated now.
- libgltf building is enabled only on those platforms
on which gltf support actually works (windows and linux)

libgltf: remove dependencies of config.h.in

It seems something is wrong with the files in the
libgltf tarball (maybe wrong timestamps?), because
config.h.in is always regenerated by make (autoheader).
It causes build problems so just remove the deps for this time.
