games/albion: Temporarily fix loading of libGL

I think this has te be fixed in <nixpkgs>, because SDL2 loads libGL at
runtime using dlopen(), but recent changes have been made so that
libGL.so is no longer in LD_LIBRARY_PATH on NixOS by default.

So until then, let's set SDL_OPENGL_LIBRARY, so that SDL2 will load it
from that path directly instead of searching in LD_LIBRARY_PATH.
