pythonPackages.pyopengl: avoid dragging in 500M of -dev packages

Only the actual shared libraries are required to be installed, and they
are imported directly by path via ctypes. The package's patchPhase
already takes care of embedding the Nix store paths of the required
libraries into pyopengl.

This reduces the transitive closure size of PyOpenGL: 622M -> 136M.
