games/bastion: Fix patching of libfmodex

I've recently moved the autoPatchelfHook execution to postFixup in
NixOS/nixpkgs@f1fbf818c4a94c67fcdb171ba00f1fef4a0aef2a, because it was
conflicting with patchelf's own setup hook.

So we now need to run the fixup of libfmodex after the autoPatchelfHook,
which we do by adding another phase in postPhases.

Alongside this I also fixed a small escaping error with ${rpath:+:},
which needs to be quoted using two single quotes.
