Tune unpacking in getPassPluginInfo() lambda

[coleramos425]

While building on HPCFund (with latest version of LLVM) I found an adjustment was made to registerOptimizerLastEPCallback in the past few days. This LLVM change adds additional parameters to the function signature which is incompatible with current implementation.

/work1/amd/colramos/audacious/fork-instrument-amdgpu-kernels/lib/InjectAMDGCNFunction.cpp:46:9: error: no viable conversion from '(lambda at /work1/amd/colramos/audacious/fork-instrument-amdgpu-kernels/lib/InjectAMDGCNFunction.cpp:46:9)' to 'const std::function<void (ModulePassManager &, OptimizationLevel, ThinOrFullLTOPhase)>' (aka 'const function<void (PassManager<Module> &, llvm::OptimizationLevel, llvm::ThinOrFullLTOPhase)>')
   46 |         [&](ModulePassManager &MPM, auto) {
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   47 |           MPM.addPass(InjectAMDGCNFunc());
      |           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   48 |           return true;
      |           ~~~~~~~~~~~~
   49 |         });

I added a variadic unroll so no matter the LLVM version being used, the lambda function should match the expected signature.
