Guillaume Bouchard 5c11e174b2 pythonPackages.pyopengl: fix runtime shared library loading failure
This closes #76822.

pyopengl 3.1.4 introduced a new logic for shared library loading: it
tests a few combinations of library name and suffix (such as .so.X).

Our previous patch was just replacing the library name (e.g. 'glut') by
the full path to the nix store. This does not work anymore with pyopengl
3.1.4 new heuristic.

This commit just keep the behavior of pyopengl but adds the nix store
path to the list of tried paths.

# https://github.com/NixOS/nixpkgs/issues/76822
# pyopengl introduced a new "robust" way of loading libraries in 3.1.4.
# The later patch of the filepath does not work anymore because
# pyopengl takes the "name" (for us: the path) and tries to add a
# few suffix during its loading phase.
# The following patch put back the "name" (i.e. the path) in the
# list of possible files.
