Hello,

Blender seems to have an issue with exporting .glb/gltf files. The issue can be
reproduced when doing:
File > Export > glTF 2.0 (.glb/.gltf) > Export

The issue seems to be in the file:
/usr/local/share/blender/4.5/scripts/addons_core/io_scene_gltf2/io/com/draco.py

`library_name` dictionnary does not have openbsd inside of it. Changing linux to
the output of Python's sys.platform (which is openbsd7) seems to fix this.

OS_VERSION: OpenBSD 7.8 (GENERIC.MP) #54
PORTS_VERSION: TOPENBSD_8_8
